摘要

提出了一种带式输送机磁场定向控制系统的小波模糊控制器。采用离散小波变换将速度误差信号分解为不同的频率分量。利用变换后的误差系数和标度系数生成电机控制信号，该控制器可以满足封闭控制系统的速度控制问题。研究了在各种动态工况下，采用小波模糊控制器的磁场定向控制方案。对传统PI控制器和所提出的小波模糊控制器的工作进行了比较。仿真结果验证了所提小波模糊控制器的有效性。所提出的小波模糊控制方法的应用可以减少电磁矩振动。

An Approach of the Wavelet-Fuzzy Controller of Vector Control System by the Induction Motor

The paper presents a wavelet-fuzzy controller of a field-oriented control system of belt conveyor drive. A discrete wavelet transform is used to decompose the speed error signal into various frequency components. The transformed error coefficients and scaling coefficients are used to generate the motor control signal The proposed controller is satisfied the speed control problem for a closed control system. The field-oriented control scheme with a wavelet-fuzzy controller under various dynamic operating conditions was investigated. The results of the comparison of the work of the traditional PI controller and the proposed wavelet-fuzzy controller are presented. The simulation results demonstrate the effectiveness of the proposed wavelet-fuzzy controller. Application of the proposed approach of the wavelet-fuzzy controller allows reducing of electromagnetic moment vibrations.
