电动汽车无刷直流电机能量回馈制动系统设计

摘要

就电动汽车能量回馈制动效率较低的问题提出了一种恒转矩模糊控制策略.首先分析了无刷直流电机能量回馈制动的基本原理,对不同的回馈控制策略进行了对比分析,设计了一个三维模糊控制器,再以该控制器为核心,在MATLAB/Simulink环境中搭建了无刷直流电机能量回馈制动系统的仿真模型,并进行仿真.仿真结果显示提出的控制策略对电机制动转矩以及能量回收达到了很好的控制效果.%Put forward a constant torque fuzzy control strategy to solve the problem of low efficiency in electric vehicles energy feedback braking.At first,made the analysis of the basic principles of energy regenerative braking of BLDCM.At the same time,a three-dimensional fuzzy controller through the comparative analysis of the different feedback control strategy was designed,and a BLDCM regenerative braking system simulation model in the MATLAB/ Simulink environment was established.Results showed that the control strategy reached good control effects to motor braking torque and energy recuperation.
