超声波电机转速控制的动态模糊建模
Dynamic Fuzzy Modelling for Speed Control of Ultrasonic Motor
摘要
Abstract
Ultrasonic motor＇s dynamic model is the precondition for the realization of speed control with high performance. The dynamic fuzzy model of ultrasonic motor system was worked out using fuzzy reasoning modelling method. The experiment was designed to obtain the data used for model identification. Based on the data, proportional spacing method was adopted to determine the structure of model. Then, the coefficients of the model were obtained using least squares method. Comparison between experimental data and calculated output of the model proves that, the model has good precision, and it can reflect the nonlinear relationship among the amplitude of driving voltage, frequency and rotating speed. The fuzzy model can be used to analyze performance of motor, and also can be used to design speed controller of ultrasonic motor.关键词
