Abstract

Shape memory alloys (SMAs) are suitable candidates in various fields of engineering. One advantage of these alloys is their capabilities in developing high strain and force. In addition to these great features, lightweight and super-elastic behavior are other traits of these materials. These specifications are of such importance and allow SMAs to be suitably used in further engineering applications. However, their intrinsic hysteresis non-linear behavior makes their usage as position actuators difficult. Despite this challenge there are various methods proposed in the literature to model the hysteresis behavior of such materials. In this paper, a GENERALIZED PRANDTL-ISHLINSKII MODEL, because of its simplicity, efficiency and inverse analytical capability, has been used for modeling the SMA behavior. In addition, the hysteresis modeling has been validated via experimental data of one of the articles. In the control section, however, two control systems consisting of PID and FUZZY SLIDING MODE CONTROLLERs have been used. Fuzzy sliding mode control system is a method that can be used in systems without mathematical model and leads to increased robustness. It is shown in this paper that by using this method, it is possible to apply a suitable control input to the system in order to remove the error signal. However, by using PID controllers, the error signal is not acceptable due to the constant controller coefficients. The results illustrate a more efficient performance of FUZZY SLIDING MODE CONTROLLER with respect to the classical PID controller.
