This paper presents simulation and experimental results for closed-loop force control of single-wire Shape Memory Alloy (SMA) actuators. The simulation uses a model derived from the frequency response analysis of SMA. Although the large-scale response has hysteresis and nonlinearities, small-signal frequency response analysis is possible on SMA wires, with detectable force response at frequencies up to 100 Hz. The model has been demonstrated to accurately predict closed-loop behaviour. A high...[Show more]
