Adaptive control of magnetostrictive actuators based on modified Preisach model

The hysteresis phenomenon exists in magnetostrictive actuators. When the hysteresis nonlinearity exists in a controlled system, the system usually exhibits inaccuracies or oscillations due to the undifferentiable and nonmemoryless character of the hysteresis. This paper considers the adaptive contro...

Summary:The hysteresis phenomenon exists in magnetostrictive actuators. When the hysteresis nonlinearity exists in a controlled system, the system usually exhibits inaccuracies or oscillations due to the undifferentiable and nonmemoryless character of the hysteresis. This paper considers the adaptive control for magnetostrictive actuators, where a modified model called "two dimensional linear interpolation Preisach model" is proposed to smoothen the discretized or estimated parameters so that the mathematical model can precisely describe the hysteresis phenomenon in discrete version. The effectiveness of the adaptive control and the modified Preisach model is verified by experiments.
