Abstract


The paper deals with modeling and control of a Shape Memory Alloy (SMA) actuator. The considered complex model is based on physical and empirical analyses of a Ni-Ti alloy straight wire actuator. Dependence on the history of the SMA actuator inputs is modeled, especially on reversing points. The SMA actuator model consists of internal hysteresis loops with memory described by nonlinear static and dynamic equations with 16 variable parameters.  Finally, the model has been simplified for control purposes.
