Relatively simple control strategy can decrease the complexity of the ultrasonic motor system, and increase the ratio of performance to cost. The algorithm of iterative learning control is simple, and its control parameters can be de- termined using little experimental knowledge. According to the particular control characteristics of ultrasonic motor, the it- erative learning control strategy was improved and speed controller was designed. Experiments show that the motor system has good iterative learning capacity. The control performance is improved continuously in the repeated learning process. The control strategy is simple and effective.
