Research of Adaptive Back-Stepping Control for a Giant Magnetostrictive Actuator

Design method of parameters adaptive controller for a giant magnetostrictive actuator is researched. According to the linear dynamic model built based on the working principle of giant magnetostrictive actuator, a parameters adaptive controller of the system is designed by integrator backstepping technology, and a strict theory proof is provided. The designed parameters adaptive controller makes sure uniformly asymptotically stable of the giant magnetostrictive actuator closed-loop control systems.
