摘要: 针对脉冲宽度调制 (PWM)整流器在特种车辆电驱动系统中电流谐波及功率脉动大的问题,提出新型预测直接功率控制策略。在传统控制策略基础上设计电流观测器,通过预测控制方法估测出由系统参数失配造成的扰动并进行实时补偿,再经电流预测计算得出下一时刻的预测电流值。建立三相PWM整流器的动态模型,通过所设计的电流观测器预测电感变化后的电流值,并将其与电流的实际值作比较,经过估计系统扰动方式补偿系统误差。仿真和试验结果表明,该PWM整流器预测直接功率控制策略能有效抑制电流谐波分量以及功率脉动,实现电感参数变化条件下的正常工作,便于控制策略在特种车辆电驱动系统中实现,且能更好地提高特种车辆电源品质。

Abstract: A predictive direct power control strategy is proposed for large current harmonics and power fluctuation of pulse width modulation (PWM) rectifier in electric drive system of special vehicle, and a current observer is designed based on the traditional control strategy. The disturbance caused by system parameter mismatch is estimated by the predictive control method and compensated in real time, and then the predicted current value at the next time is calculated by current prediction. A dynamic model for three-phase PWM rectifier is established. The current value after change in inductance can be predicted by the designed current observer and compared with the actual current value. Finally, the system error is compensated by estimating the system disturbance. Simulated results show that the proposed predictive direct power control strategy can be used effectively to suppress the current harmonic component and power pulsation, realize the normal operation under the condition of inductance parameter change, and better improve the quality of special vehicle power supply,and is available for the special vehicle electric drive system.
