在混合动力汽车中，采用DC/DC变换器的直流环节电压可变系统，通过提高直流环节电压来提高系统的功率。作为DC/DC变换器的控制方法，提出了仅使用比例补偿器的电压反馈控制。控制系统设计简单，但直流母线电压可能会出现稳态误差。本文提出了一种比例积分补偿器来消除直流侧电压反馈控制器中直流侧电压的稳态误差。此外，在设计补偿器的增益时，考虑了干扰的频带。通过在缩减模型上的实验验证了该方法的有效性。
DC link voltage variable systems with DC/DC converter are used in hybrid electric vehicles for improving the power of the system by boosting the DC link voltage. Voltage feedback control using only proportional compensator has been proposed as a control method for the DC/DC converter. The control system can be easily designed, but there is a possibility that a steady‐state error occurs in the DC link voltage. In this paper, a proportional integral compensator is proposed to eliminate the steady‐state error of the DC link voltage in DC link voltage feedback controllers. In addition, when designing the gain of the compensator, the frequency band of the disturbance is considered. The proposed method is verified through experiments on the downsizing model.
