Abstract

Research on the use of Shape Memory Alloy actuators for miniature applications is interesting due to their high power-to-weight ratio and self-sensing capabilities based on resistance-strain models. Hysteresis behaviour in addition to slow cooling response makes the control a major problem to be addressed. This work investigates the applicability of different control approaches in combination with both external sensing and resistance-strain model based prediction of the actuator position. The problem of model dependence on external conditions and applied load is also outlined.
