摘要：
Aiming at the non-linearity and hysteresis of giant magnetostrictive actuator (GMA), two numerical realization of Preisach model by density function method (DFM) and F fuction method (FFM) are present. Experiment and simulation show that FFM is better than DFM over predict precision of hysteresis loops. To make the Preisach numerical model in application to practical control of GMA, a real-time numerical compensation algorithm for preisach model is pointed out, and a PID plus Preisach feedforward compensation (PFC) control model is build up, open-loop, general PID and PID plus PFC are independently applied to GMA for the position tracking and trajectory tracking. Experiment results reveal that PID plus PFC has faster response, higher precision of position tracking and trajectory tracking than open-loop and general PID, 3μm position tracking error and 2μm trajectory tracking error in the range of 100μm can be attained by PID plus PFC.
