| Abstract: | Ultrasonic motor is a kind of control object with obvious time-variable nonlinearity.In order to improve its speed control performance,some adaptive control strategies are adopted.In this paper,a model reference adaptive speed controller is designed for ultrasonic motor.The controller takes drive voltage's amplitude as the control argument,and is designed using input-output variables according to Lyapunov stability theory.Novel method of on-line adaptive-rate regulation and a differential feedforward compen... |
