Abstract

The Macro/Micro Dual-drive experiment system with numerical control working platform is built. The ball screw drives the working platform macroscopic motion. The giant magnetostrictive actuator (GMA) is used to compensate the microcosmic motion error. It is proposed that the transfer function of the GMA cascaded the rate-independent hysteresis model to structure GMA system model. The variable structure control based on the decomposition is proposed, and the adaptive control law for the variable structure control is deduced from the Lyapunov stability theorem. The experiment results show that the motion error of ball screw is compensated after a dynamic compensation control is operated to the GMA, and the motion precision of the working platform is markedly improved.
