The positional information of principal and subordinate's electric pole is to position deviation stable when there is first time overshoot relative to main electric pole position from electric pole position
When time minimum and overshoot minimum, Td_pParameter adjusts completion.
4) K that will have been adjusted in 1) stepp_pIt is multiplied by the T adjusted in 0.8,2) stepi_pAnd 3) adjust in step
Td_pFinal argument of the parameter as the position PID controller.
The control control effect test of present example is carried out in the electric tail gate of certain type SUV automobiles.For tail-gate electricity
The dynamic process opened, for the first time test are independently controlled respectively for left and right electric pole, and what the left and right electric pole received is same
Speed command, the tracking to speed command is completed by respective velocity close-loop control respectively.In this time test, tail-gate is controlled out
Open at 2/3rds of maximum opening, the positional information of the left and right electric pole is as shown in Figure 5A.Second of test then adds this
The described position Synchronous motion control method of invention, real-time tracking is carried out to the position of main electric pole from electric pole.In this time test, tail
Door is opened at maximum allowable angle by control, and the positional information of left and right electric pole is as shown in Figure 5 B.As seen from Figure 5, if
Deviation be present without the position between position synchronization control, tail-gate or so electric pole between the left and right electric pushrod of tail-gate, and should
Deviation is constantly accumulated with the increase of tail-gate opening angle, can be caused two force unbalances of tail-gate, must if things go on like this be made
Into the deformation of tail-gate.And when performing position synchronization control of the present invention to left and right electric pole, even if tail-gate is opened to most
Big aperture, the final position deviation between the bar of left and right still meet design requirement, avoid tail-gate because left and right bar position is different
Step causes the situation of deformation to occur, and indicates the validity and practicality of the method for the invention.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, all any modification, equivalent and improvement made within the spirit and principles of the invention etc., all should be included
Within protection scope of the present invention.
