The magnetostrictive actuator is a widely used precision smart actuator; however, the micro-positioning and tracking performance of it is limited due to the inherent dynamic nonlinearities. In order to improve the tracking performance of actuator, a hybrid control strategy comprising a preliminary rate-independent hysteresis compensation and a further adaptive filter controller is developed. The generalized...
The spline adaptive filter (SAF) is recently proposed to identify wiener-type nonlinear systems, which consists of an infinite impulse response filter followed by an adaptable look-up table and interpolated by a local low-order polynomial spline curve. To improve the performance of magnetostrictive actuator (MA), SAF is introduced to identify the hysteresis model of MA in this paper. In addition,...
