具有能量回馈的混合动力汽车电动机控制器设计

设计了以TMS320LF2407作为中央处理器的无刷直流电动机控制器,并将该控制器应用于混合动力汽车的驱动系统中。控制器设计为转矩控制方式,给汽车提供连续可调的起动、助力和制动转矩;为了提高能源的利用率,控制器采取能量回馈制动的方式,将制动时的能量回馈到电池。实验结果表明,控制器控制性能好、结构简单、工作可靠,可以很好地满足混合动力汽车的驱动要求,并能够和汽车其它各功能部分协调地工作。

The Design of Hybrid Electric Vehicle Motor Controller with Energy Regeneration

A design of hybrid electric vehicle (HEV) brushless DC motor controller based on TMS320LF2407 with energy regeneration,which is used in the drive system of the HEV. To give the HEV any magnitude torque within rated torque for starting aid and braking, the controller is implemented with direct torque control. To obtain the optimal energy utilization, the controller controls the regenerated energy feeding to the battery when the motor operates in braking mode. The experimental results show that the controller can satisfy the drive requirement of the HEV and has good performances.
