| Research Abstract |
A new hysteresis model which can describes the nonlinear relation between the input and output of the smart material based actuators, such as piezo actuator and magnetostrictive actuator, has been proposed. The advanced control algorithm for the systems preceded by hysteresis has been synthesized. The stability of the closed-loop system is guaranteed and the output tracking error is analyzed. The effectiveness of the proposed algorithm has been demonstrated by the high precision control preformance of the nano-stage driven by magnetostrictive actuator.
