超声波电动机MIT模型参考自适应转速控制

摘要

The cost of ultrasonic motor control system including the driving circuit can be reduced by using a relatively simple motion control algorithm,so as to promote the mass production of ultrasonic motor.Aiming at this purpose,a simple model reference adaptive control strategy used to control speed of ultrasonic motor was proposed.This strategy has a small amount of calculation and moderate capacity of adaptive.Therefore,the performance-to-price ratio of the system can be increased.%采用相对简单的运动控制算法,有助于降低包含驱动控制电路在内的超声波电动机系统的成本,从而推动其产业化.基于这一目的,给出一种模型参考自适应控制策略用于超声波电动机转速控制.该策略计算量小,并具有一定程度的自适应能力,提高了系统性价比.
