An actuator design and a function scheme are developed. A control algorithm of a
cyclic actuator is considered. We provide experimental results on the control algorithm and
the actuator. The actuator operating range is 60œ. The actuator sped is ~ 1 degree/second. The
actuator operating is stable in any rotation angle in operating range.
Keywords: shape memory effect, Cu-Al-Ni single crystals, cyclic rotary actuator
