摘要:A kind of giant magnetostrictive actuator (GMA) with two-end outputs is designed. The mechanical structure and its working principle are presented, and the static characteristic experiment of the GMM rod is adopted to determine the linear working range. Based on the above, the mathematical model of the GMA is established according to the piezomagnetic equation and Newton's second law. Then the research on response performance of the open-loop system is executed and the results indicate that the overshoot and the settling time are relatively large. To improve the dynamic response speed and the steady-state output performance, the NIP controller is designed to form a closed-loop control system. The simulation study on the control performance of the closed-loop system is carried out in this paper. When the (PID mu)-D-lambda controller is adopted, the results demonstrate good control performance with an overshoot of step response of 1.77% and a settling time of 2.73x10(-4)s.
