摘要
超声波电动机的转速控制存在明显的时变非线性特征。为得到较好的控制性能,设计了基于模糊逻辑的模型参考自适应PID转速控制器,实现了基于参考模型跟踪误差的PID控制参数在线自适应调节。实验表明,转速跟踪性能优于固定参数PID控制器。
Obvious time-variable nonlinearity exists in ultrasonic motor speed control.A model reference adaptive speed controller using fuzzy logic was designed to obtain better control performance.It realizes the online adaptive adjustment of the control variables based on the tracking error of reference model.Experiments indicate that the speed control performance is better than that of the constant PID controller.
