Actuator control method and control device

摘要

A control device for control an actuator comprises a "shape-memory alloy that recovers to prescribed memory dimensions' and "a force application means that applies an external force to the shape-memory alloy and changes its dimensions' has a pre-heating means that, prior to the control of a driven member by the actuator, pre-heats the shape-memory alloy to a temperature at which the shape-memory alloy begins to change its shape or to a slightly lower temperature relative thereto.
