Super elastic alloy (SEA) has the characteristic of two-way deformation by heating and cooling under prestressed condition. The characteristic makes it possible to use as an actuator of flexible, compact, and quiet. In this study, objective is to develop the actuator made of prestressed SEA. Temperature, strain-stress and phase of the SEA interacts Metallo-thermo-mechanical. SEA has a nonlinear deformation behavior because by this. This characteristic makes it hard to control practical SEA actuator, and impedes the spread of SEA actuator. Therefore, this study constructed a control theory depending on the material characteristics of the SEA and conducted a feedback control of the SEA actuator for practical use.
