PID Control of an Electric Clutch Actuator

摘要

A PID controller is designed for an electric clutch actuator, which adopts ball screw as the speed reduction mechanism.Ball screw has high transmission efficiency.However, it does not self-lock.Moreover, the nonlinear friction force, load force, and the nonlinear characteristics of the motor drive circuit increase the difficulty of the position control of the actuator.Model-based control development is used, and the PID coefficients are calibrated based on a simulation model.Then the tuned parameters are used for experimental test.Through experimental results, it is shown that the designed PID controller provides satisfied position tracking performance of the electric clutch actuator.
