For the ease of the simplification of robot model, in the research of advance model, following several presupposition and consideration are mainly done：
It is reverse-biased to anti-angular force F, holding power N and force of sliding friction f of the wheel by ground and two gravity of leg arm and making for holding power
It is located at point on same point, the contact point for being all located at universal wheel and ground；Due to force of rolling friction flAnd frFar smaller than front-wheel
Force of rolling friction ffront, so ignoring f hereinlAnd frMoment loading；Robot is when carrying out leg arm swing commutation, extroversion wheel
Deviation angle β value moment converts and reaches predetermined value；Advance model only considers the motion conditions of robot in the horizontal plane.
Modeling method process is as follows：
1. carry out dynamic analysis
Force analysis is carried out to robot with reference to sine and cosine theorem, power and torque equilibrium equation formula is set up, can obtain:
llNl·cos(Ψ2+θ2l)+lrNr·cos(Ψ2+θ2r)=
GpLG+Glll·cos(Ψ2+θ2l)+Grlr·cos(Ψ2+θ2r) (1)
+Flh·sin(φl+βl)+Frh·sin(φr+βr)
During robot straight ahead, leg arm mainly does open and close movement, and in order to ensure its exercise performance stability and
The reasonability of motion, the leg arm of robot makees symmetric motion.Therefore the unification of variable is carried out here：
Nl=Nr=N, Gl=Gr=G, θ2l=θ2r=θ2
θ1l=θ1r=θ1, ll=lr=l, ωl=ωr=ω
φl=φr=φ, βl=βr=β, Fl=Fr=F, fl=fr=fleg
The thrust during 2. pair robot advances is analyzed
Robot thrust suffered when advancing：
Fforward=2Fsin (φ+β)=2Ntan λ sin β sin (φ+β) (2)
Here set, β deviates equilbrium position inwardly, is negative value；Deviate equilbrium position outwards, be on the occasion of.
Composite type (1) and formula (2) can be obtained：
3. the resistance that pair robot is subject to is analyzed
Robot is when advancing, the force of rolling friction f mainly produced by front and back wheel and groundrollAnd robot and sky
The resistance f that gas friction is producedair, robot is by total resistance：
F=froll+fair=(Gp+2G-2N)μroll+2Nμroll·cos(φ+β)+KairVp (4)
Here coefficient of rolling friction μ is givenroll=0.02, coefficient of air resistance Kair=0.1.
4. carry out the calculating of barycenter acceleration
Assuming that the barycenter acceleration in robot kinematics is ao, then can be obtained by theorem of impulse：
Simultaneous formula (4) and formula (5) can be obtained:
Simultaneous formula (3) and formula (6) can be obtained：
5. obtain the influence factor of barycenter acceleration
It can be seen from formula (7) only leg arm pivot angle φ and it is reverse-biased to angle beta be what two variable quantities, i.e. robot advanced
Acceleration reverse-biased can be determined from pivot angle φ and to angle beta.And pivot angle φ is relevant with leg arm slew rate ω, it is reverse-biased to angle beta mainly with it is universal
Take turns related to the frictional force that ground is produced, therefore the control of acceleration can be realized by controlling slew rate ω during control, so that
The speed that control machine people advances.The formula provides feasibility for the control of robot, is that the control of robot specifies direction.
6. the situation for the frictional force that pair robot is subject to is analyzed：
Anti- angular force when robot advances：
F=Ntan λ sin β (8)
And this power is mainly derived from the frictional force that universal wheel is produced with ground, this frictional force and universal wheel rotating direction are just
Hand over, i.e., it is vertical with rolling friction force direction.According to the different situations of leg arm swing, frictional force has static friction and sliding friction
Two kinds of different existence forms, during sliding friction, have：
F=N μslide=Ntan λ sin β (9)
Wherein μslideFor the coefficient of sliding friction.
Then
μslide=tan λ sin β (10)
Take μslide=0.25, λ=19.5 °, β=π/4 can be obtained.
Because maximum static friction force is more slightly larger than force of sliding friction, and ground is more smooth, it is big must be more.Robot of the present invention is real
Mainly walked when testing on ceramic tile, by testing 1.225 times that maximum static friction is about sliding friction, then obtain βmax=
π/3, this is the maximum that β can reach.
In summary, the major influence factors of influence robot pace have：
(1) swing arm pivot angle scope
With reference to robot mechanostructural property itself, when robot pivot angle φ is too small or excessive, it can all cause robot
Because the imbalance problem of center of gravity is fallen down, and excessive pivot angle can also hinder the motion of robot.Selected by test, we
Robot pivot angle φ scope is taken as [π/40 of 3 pi/2 0,11], its swing arm amplitude of oscillation Amp=π/8, now robot operation is more
It is stable, this amplitude of oscillation is all used when hereafter being analyzed, is repeated no more.
(2) swing arm slew rate
Swing arm slew rate is to influence the major influence factors of the robot speed of service, and swing arm slew rate has interior slew rate and outer slew rate two
The situation of kind.
(3) dwell time
Skill during human body breaststroke is used for reference, when pendulum reaches defined minimum position in robot leg arm, it is necessary to pause one
The fixed time.Certain dead time can make it that the motion of robot is more reliable and more stable, leg arm conversion it is more smooth, no longer that
It is stiff.By test, the dwell time is chosen to be that StopTime150m is more suitable, now the operation conditions of robot compared with
It is good.
Influence of the interior slew rate degree of robot leg arm from outer slew rate degree to robot pace is different, in order to understand two
Influence relation of the person to robot speed, has carried out a series of emulation and experiment, has been obtained finally by Function Fitting such as ShiShimonoseki
System：
RobotSpeedsimulation=0.4017 ωin-0.01561ωin 2+0.01339ωout+0.004193ωout 2 (11)
RobotSpeedexperiment=0.3645 ωin-0.01908ωin 2+0.06387ωout-0.016930ωout 2 (12)
It is real from formula (11) and formula (12) it can be found that outer influence of the slew rate to itself speed of robot leg arm is more faint
Test and can seriously slow down the speed of service of robot when slew rate is smaller outside middle discovery；And the outer slew rate of excessive leg arm can cause universal wheel
Frictional force between ground is changed into sliding friction from static friction, and this will make it that the swing of leg arm becomes shake, leg arm pivot angle
Change procedure becomes extremely unstable, is unfavorable for the operation of robot, and some problems are also increased to control.And suitable leg arm
Outer slew rate, the frictional force is then that the swing process of leg arm in the case of static friction, static friction is then smooth, at this time robot
Motion is stablized relatively, and control is relatively easy, largely also protects mechanical structure and the executing agency of robot, therefore,
Certain outer pendulum speed omega is taken in controlout=0.78rad/s.
The method for control speed of the frog board robot of the invention of the present invention includes herein below：
(1) method for control speed is as follows during robot descending：
When robot descending, if without control of braking, the speed of robot will infinitely increase, and cause certain danger
Danger.During descending, motor 3 need not be rotated to drive leg arm 8 to be swung, can be with by angular transducer 2
The pivot angle of frog board robot leg arm 8 is measured, during descending, larger pivot angle and then guarantor can be turned to by motor 3
Hold motionless, be so beneficial to the stability for keeping descending.During downhill running, turn of the rotational band activity code disk 7 of front-wheel 9
It is dynamic, the velocity of rotation of front-wheel 9 can be measured, and then know the pace of robot, when the pace of robot is more than certain
During the threshold value of individual setting, now by the controller control brake steering wheel 5 of robot brake block 6 can be driven to be carried out with front-wheel 9
Friction is to realize deceleration, when the speed of frog board robot is reduced under this threshold value, then control brake steering wheel 5 unclamps, so
The speed of robot will be stablized in this threshold range set in advance, and the speed of robot will not cause because of too big
The generation of dangerous situation.
(2) speed control smoothly of robot：
As shown in Figure 3, it is the structured flowchart of speed control system, whereinFor given speed, V (t) is robot
Actual motion speed,For the rotating speed of target of robot, n (t) is the actual speed of robot.The speed control of robot
It is controlled using two closed loops, inner ring realizes the control to robot motor's rotating speed using traditional PID controller, outside
Ring realizes control to robot bulk velocity using fuzzy PID algorithm, wherein due to outside robot leg arm slew rate degree to machine
The bulk velocity influence of people is smaller, therefore outer slew rate degree keeps constant in the process of running for robot, is realized by bottom PID, only
Fuzzy PID is just used during being put in robot.As shown in Figure 4, it is the controller chassis of fuzzy controller
Figure, fuzzy-adaptation PID control is exactly the concept that fuzzy control is introduced in traditional PID control theory.Controller is by velocity error e
With error rate ecAs input quantity, then velocity error e and error rate ecSize carry out Fuzzy processing, then pass through
The calculating for crossing membership function searches out the corresponding k of fuzzy reasoning table set in advancep,ki,kdParameter, is then pushed away by fuzzy
Reason and anti fuzzy method calculate the amount of being accurately controlled and carry out controlled motor, to realize the control to robot speed, make robot
Speed is stablized in given speed alwaysIn certain scope.
Experimental verification：As shown in Figure 5, it is the fuzzy control in the case where given robot pace is 0.5m/s
Slew rate degree keeps outer slew rate degree constant for just, outer slew rate degree is negative in experimentation in the control effect of device processed, definition, interior
Slew rate degree is changed in real time according to the output of fuzzy controller, it can be seen that robot can be with another swing arm cycle
Given speed is reached, the actual speed of robot can be tracked to given speed.As shown in Figure 6, it is given speed
During change, the step response of robot and the velocity variations situation of stable state, it can be seen that when given speed changes, control
Device can make quick response, robot bulk velocity is quickly approached given speed, and the ripple near robot given speed
It is dynamic.
The embodiment of the present invention is described above in association with accompanying drawing, but these explanations can not be understood to limitation
The scope of the present invention, within the spirit and principles of the invention, any modifications, equivalent substitutions and improvements made etc. all should
Within protection scope of the present invention.
