双无刷直流电机同步控制的Simulink仿真

Simulink Simulation of Synchronous Control of Two Brushless DC Motors

提出了一种单控制器控制双电机驱动电动汽车的方法,其中两个电机均采用双闭环控制策略。在电流环引入模糊控制,由模糊控制算法直接给出电机控制量。控制方案可以从算法上实现电子差速,具有良好的同步控制效果,同时可以满足控制精度的要求。主要针对这一控制策略分别就汽车直行和转弯过程进行了Simulink仿真,以汽车转角0°和120°为例。仿真结果表明方案在同步控制和电子差速控制方面均有较好的效果。

This paper presents a method of using the single controller to control two motors to drive electric vehicles, whereby both motors adopt dual closed loop control strategy. Fussy control is introduced to the current loop, and the fussy control algorithm directly gives control variables. The control scheme can realize electronic differential through the algorithm, produces good effect of synchronous control, and can meet the requirement for control accuracy. Simulink simulation is completed during direct movement and turn of the vehicle at 0^0 and 120^0. The simulation result shows that the scheme can produce good effects in synchronous control and electronic differential control.
