Abstract: Ultrasonic motor is difficult to achieve an ideal stability and precision due to the nonlinear characteristics. In order to improve control precision and stability, a BPNN (BP neural network) -based control strategy was proposed to control the rotating-speed of the ultrasonic motor. After some simulations, an experimental system was setup and some experiments were performed to testify the control algorithm. The experimental results show that the BPNN-based control strategy can achieve rapid response and high precision speed tracking; the control error is less than 2 r/min.
