Abstract :
This paper deals with the L2 stability of a shape memory alloy actuated position control system, based on a single wire under constant axial load. Presuming a controller has certain specific dissipativity characteristics, it is shown that system stability can be guaranteed for a large class of controllers. In particular, the results can be used to show stability under approximated PID, PI and PD control. The result is used to find a stabilizing PI controller, and the corresponding experimental data is shown
