摘要
针对超声波电动机的转速控制特点,设计了超声波电动机模糊转速控制器。采用蚁群算法对模糊控制器中的模糊规则进行离线优化,确定合适的模糊控制器参数。在实验过程中,针对不同转速情况下的控制性能差异,给出了模糊控制器输出比例因子的在线调节方法,得到了较好的转速控制效果。
Aiming at the speed control characteristics of ultrasonic motor, a fuzzy speed controller was designed for ultrasonic motor. Rules of the fuzzy controller were optimized offline using ant colony optimization, and the appropriate parameters of fuzzy controller were ascertained during the process of optimization. According to the difference between the responses with different speed values, a kind of online tuning method was proposed to modulate the proportional coefficient. Experiments indicate the validity of the proposed controller.
