摘要
分析了PWM整流电路各种控制方法的优缺点,提出了将空间电压矢量控制和定频滞环优化矢量电流控制相结合的复合控制策略,既保证了系统有好的静态特性,又保证了系统的快速跟随性。对空间电压矢量方法进行了改进,在不改变系统输出特性的前提下,使开关频率降低了 50%。仿真结果证明复合控制方法使系统具有控制精度高,调节时间短,超调量小等优点,能够满足混合电动汽车能量回馈系统的要求。
This paper analyzed the advantages and disadvantages of several PWM rectifier control methods. A hybrid control strategy was proposed, which based on the combination of the novel voltage space vector control and the optimized fixed frequency hysteretic vector current control. The proposed scheme guaranteed the good static characteristic and the fast dynamic respond. Maintaining the output character of the system, the voltage space vector control was improved which made the switching frequency decrease 50%. The simulation results prove the advantages of the better static and dynamic characteristics, high accuracy, short adjustment period and small overshoot, which meet the requirements of the energy feedback system of hybrid electric vehicle.
