NEW DEVELOPMENT ON SHAPE MEMORY ALLOYS ACTUATORS

Roberto Romano, Eduardo Aoun Tannuri

Abstract

The present paper presents the development of a mechanical actuator using a shape memory alloy with a novel cooling system based on the thermo-electric effect (Seebeck-Peltier effect). Such a method has the advantage of reduced weight and requires a simpler control strategy as compared to other forced cooling systems. A complete mathematical model of the actuator was derived, and an experimental prototype was implemented. Several experiments are used to validate the model and to identify all parameters. A robust and nonlinear controller, based on sliding-mode theory, was derived and implemented. Experiments were used to evaluate the actuator closed-loop performance, stability, and robustness properties. The results showed that the proposed cooling system is able to improve the dynamic response of the actuator.
