Abstract: Aiming at the problem that the differential term in Newton's learning law is difficult to determine and affect the control performance, the secant method in numerical analysis was used to give the secant learning law and it was used for iterative learning speed control of ultrasonic motor. Some practical improvement methods for the secant iterative learning control strategy were given to solve the problems in practical applications. Experiment results show that speed control performance of ultrasonic motor was improved during the learning process, and the control strategy is simple and the effect is good.

Key words: ultrasonic motor, speed control, iterative learning control, secant method
