Abstract: The nonlinear secant iterative learning control strategy was used for ultrasonic motor position control and was improved to adapt to the time-varing and nonlinear characteristics of USM. To get the desired performance, the writer determined the control parameter of nonlinear secant iterative learning position controller used the mushroom propagate optimization algorithm. The results prove that the nonlinear secant iterative learning control strategy which with good performance and low complexity of control strategy is suitable for the motion control system of ultrasonic motor.
