DEVICE FOR CONTROLLING AND METHOD FOR CONTROLLING SHAPE-MEMORY ALLOY WIRE ACTUATOR

摘要

This method for controlling a shape-memory alloy actuator that uses a shape-memory alloy wire that contracts by means of electrical heating and extends by means of cooling has: a driving step (S201) that electrifies the shape-memory alloy wire; a detection step (S202) that detects the resistance value of the shape-memory alloy wire; and a determination step (S203) that determines whether or not the resistance value detected in the detection step is at the contraction limit of the shape-memory alloy wire on the basis of the thermal resistance of the shape-memory alloy wire.
