摘要：AbstractA novel kind of I-AMTs is adopted for pure electric vehicle, which uses overrunning clutch to replace the sleeve to realize smooth shift without power interruption. A nonlinear-feedward-feedback controller is designed for its electric clutch actuator that includes a dc motor, a set of worm gear, worm and linkage mechanism to implement the motion control. However, the nonlinear load force and the nonlinear characteristics of linkage mechanism increase the difficulty of controller design. The designed controller includes two parts: the feedforward controller was designed to settle system nonlinearities and the feedback controller was designed to guarantee the reliability of the controller. Experiments result shows that, compared with PID controller, the designed controller can provide better performance and keep the system stable at the same time.
