Abstract: Abstract An optimal control method is proposed for shape memory alloy actuators in smart structures. The method is capable of compensating for the hysteretic behavior present in these materials and thus qualifies for high frequency applications where conventional methods fail. Furthermore, a version has been developed, which is fully real-time capable. It is based on a parametric sensitivity analysis of nonlinear programming problems and is demonstrated to work very robustly for a wide range of parameters.
