Analysis of Electric Acutator for Light Vehicle with AMT

The light vehicle transmission types have been changing during recent years and the rate of change is currently accelerating as use of an automated mechanical transmission (AMT). For AMT transmission,the clutching characteristic is the key technology and the driving characteristics of its actuator is related to the AMT performance directly. In this paper, the control performance of the clutch actuator was studied, and the basic structure of the clutch electric actuator and working principle were analyzed. Through the basic parameters of clutch actuator, the mathematical model of actuator was established. Using Matlab / Simulink Fuzzy blocks, the fuzzy immune PID controller simulated the electric actuator mathematical model and servo control system of clutch, and after comparing the experimental results with simulation results, confirming that the electric actuator meets the clutch requirements.
