Abstract
Hysteresis phenomena often degrade system performance such as giving rise to undesirable inaccuracy. Shape Memory Alloy (SMA) actuators are chosen as an example of a plant with hysteresis and a control system to compensate the hysteresis is proposed in this paper. Firstly, a model which represents the temperature hysteretic property of SMA and its inverse model are designed. Secondly, a controller is proposed to compensate the hysteretic property by using the inverse model. Lastly, this method is applied to control the electrical resistance of SMA, which reflects its state, and the usefulness of the controller is confirmed experimentally.
