Analysis On EPS Mechatronic Fuzzy-PID Closed-loop Control System

摘要：

The electric power steering (EPS) system is the mechatronic control system. The corrent PID control is the closed loop control with the error between the aim corrent and the motor armature backfeed corrent, and the fuzzy PID control is the mechatronic closed-loop system by the error which reflect the change of the turning-axis. In this paper we present the development of a vehicles EPS control, based on a double layer closed-loop fuzzy-PID controller which consisted the corrent backfeed inner loop and the moment backfeed outer loop. The output of the fuzzy PID control is used as the assist-force target value. Then the corrent PID control is put up so that the aim- moment can be track fastly. The simulation results show that the strategy is more effective in improving the tracing ability and stability of EPS.
