摘要
为提高无刷直流电动机(BLDCM)控制系统的精度,本文根据电机的数学模型,基于Matlab仿真平台构建了BLDCM电流、转速模糊PI复合控制的双闭环控制系统的仿真模型。该模型采用了一种基于分段线性化的思想,利用Simulink中的Look-Up Table对梯形波感应电动势和电磁转矩进行快速建模的方法。仿真结果表明,该模型准确易行、控制精度高,为实际BLDCM控制系统的设计和调试提供了有效的工具。
In order to improve the precision of the Brushless I3（3 motor （BLI^M） control systems, a simulative model is built on a timing system of double closed loops with current and the speed fuzzy-PI control in Matlab by analyzing the corresponding mathematical model. Based on the method of Piecewise Linear Curves, the Look-Up Table block in Simulink is applied to quickly realizing the modeling of trapeziform-wave inductive EMF and Electromagnetic Torque. The results show that the modeling method has a higher control precision and can easily be applied, so it offers effective methods and means to designing and debugging actual motors.
