摘要
针对传统电动汽车直流电机驱动系统存在无法自动弱磁的问题,采用复合励磁的方式,设计了一种依据电动汽车驱动要求对复合励磁直流电机进行最优控制的驱动系统。通过软硬件的设计,仿真和实验,结果表明:该驱动系统较好地解决了自动弱磁问题,并具有抗干扰能力强、调节速度快等优点。
In view of the traditional electric vehicle DC motor drive system has not automatic weak magnetic problem using composite excitation method,a based on the requirements of electric vehicle drive of the hybrid excitation DC motor drive system optimal control is designed.Through the hardware and software design,simulation and experiment,the results show that the system can solve the problem of weak magnetic field,and has the advantages of strong anti-interference ability,fast adjustment speed and so on.
