摘要
针对超声波电机构成的速度伺服系统采用了一种新的控制方案———自校正模糊PI控制。该控制器由模糊控制环节、PI控制器、自校正环节构成。PI控制器的比例增益KP 和积分增益KI 由模糊控制规则确定 ,并且通过修正因子在线自校正来优化模糊控制规则。实验结果表明该控制方案效果好 ,简单易行 。
A new scheme of self-tuning PI control for the speed servo system composed by the ultrasonic motor is proposed in this paper.The controller is made up of fuzzy control part, PI controller and self-tuning regulator. The proportional gain and integral gain of the PI controller are determined by fuzzy control rules, and the rules are optimized by on-line self-tuning modifying factors. The experiment result shows that this control scheme is efficient,simple and general.
