Abstract
This paper presents the classical Preisach modeling of the hysteresis and tracking control of a Thunder actuator system. The numerical expressions of the classical Preisach model were presented in details for different input variations. It was found that the saturation output values in these numerical expressions could be cancelled out. A series of tests were conducted to study the hysteresis properties of the Thunder actuator system. The classical Preisach model was then applied to simulate the static hysteresis behavior of the system. Higher-order hysteresis reversal curves predicted by the classical Preisach model were verified experimentally. The good agreement found between the measured and predicted curves showed that the classical Preisach model is an effective mean for modeling the hysteresis of the Thunder actuator system. Subsequently, the inverse classical Preisach model was established and applied to the real time microposition tracking control of the Thunder actuator system. Real time tracking control was achieved by combining a lead-lag feedback controller and the inverse model. On a moving range of 0-0.1mm, the tracking error with hysteresis compensation was less than 2.5%, compared to an error of up to 10% without hysteresis compensation. Experimental results showed that control accuracy with hysteresis compensation is greatly improved compared to that without hysteresis compensation.
