Time-Slicing Control Strategy for Rotary SMA Actuators

다국어 초록 (Multilingual Abstract)

A new control strategy that can be applied efficiently to rotary SMA actuators was investigated. This type of controller primarily focuses on adjusting the amount of time to apply a voltage or current to actuators while the traditional controllers have been widely used to compute amplitude of signals fed to the actuators. To prove the effectiveness as well as the capability of the proposed strategy in controlling rotary SMA actuators, a simple time-slicing PID controller was developed. The experimental results showed that the proposed time-slicing PID controller attained a better tracking performance compared to the traditional one.
