N2 - Giant magnetostrictive materials (GMM) are widely used in high-frequency response actuators, but the inherent hysteresis nonlinearity of the material often hinders the precise output displacement of giant magnetostrictive actuators (GMA). In order to improve the displacement output accuracy of the giant magnetostrictive actuator, this paper proposes a temperature-adaptive feedforward compensation-fuzzy PID control (TFFC-FPID) algorithm. This paper first establishes a more accurate system model, and based on this, deduces the output of feedforward compensation, and obtains the relevant parameters of the fuzzy PID through trial and error. Finally, through experiments, the average displacement output of the actuator under closed-loop control is obtained. The mean relative error is 12.08%, the root mean square error is 0.0013mm, and the error is within the acceptable range, verifying the effectiveness of the control algorithm.
