It is effective for improving the temperature response of SMA actuator to raise the heat treatment temperature of the SMA elements or to give long-term low temperature aging treatment of elements. And the ribbon shaped element with large superficial area is more effective for improving temperature response than wire element. The resistance feedback control system using the method of setting off-time has proposed that positioning can be set and retained at an arbitrary position. The effect of positioning characteristics on control distance and external loads are investigated. Furthermore, the new resistance control system without setting off-time has proposed. This new system can be controlled position with accuracy less than 10μm. New kinetics and constitutive equations which are available to plastic deformation region and the heat transfer model in consideration with ambient temperature and phase transformation latent heat have proposed and the displacement with time is simulated by these equations and model. The calculation results coincide with those of experiments well. The three-dimensional positioning system using these techniques was produced and its operability and controllability were inspected.

提高SMA元件的热处理温度或对元件进行长期低温时效处理对于改善SMA执行器的温度响应是有效的，而大表面积的带状元件对于改善温度响应更为有效。采用设置关断时间方法的电阻反馈控制系统提出了可以在任意位置设置和保持定位特性的效果。此外，还研究了新的电阻。提出了无需设置关断时间的控制系统。新系统可以以小于10μm的精度控制位置，提出了适用于塑性变形区域的新动力学和本构方程以及考虑环境温度和相变潜热的传热模型，并通过这些模型模拟了位移随时间的变化。建立了基于该技术的三维定位系统，并验证了其可操作性和可控性。
