| 摘 要： | 针对双PWM电机驱动系统中，因电机运行状态的频繁改变而引起．的直流母线电压的波动问题．通过分析直流电压波动的原因，提出了一种基于EL模型和负载功率前馈的双PWM控制策略．通过对整流器进行非线性建模、加入直流稳态电压补偿和采用负载功率预测方式，从而可以用较小的直流电容获得稳定的直流电压和网侧单位功率因数，实现能量的双向流动，仿真分析验证了该方法的正确性．

| Abstract: | For fluctuations of the DC bus voltage in dual PWM motor drive system, which is caused by the frequent changes in motor running, its generation mechanism is analyzed. A new control strategy for dual PWM system is proposed, which is based on EL model and the load power feedforward. By using DC steady state voltage compensation and the Power load forecasting, the stable DC voltage and the unity power factor is obtained based on a amall DC capacitor. Besides, the bidirectional energy flow is achieved. The simulative result verified this method. |
