Design and development of magnetostrictive actuator Chang, Jye-Kai
Abstract
In this joint project between NRC and UBC, the author has developed an actuator using Terfenol-D, an optical precision displacement sensor, and a few control strategies. These control strategies include proportional-plus-integral-plus-derivative (PID), cascaded PID, and sliding mode control strategies. Each of these controllers was designed and tested experimentally on the actuator. The controllers were very difficult to design because the dynamics of Terfenol-D has hysteresis. The system with the designed PID controller showed sign of instability under load. However, the designed cascaded PID and the designed discrete-time sliding mode controllers are capable of controlling the actuator under loaded condition and fulfilling the requirements of NRC. Real-time experimental results are attached in chapter 5.
