摘要
PWM流系统具有网侧电流谐波含量低、功率因数高、能量双向流动和直流电压稳定等优点,详细分析了双闭环直接电流控制和直接功率控制的算法基本原理,并对这两种控制算法的控制结构以及参数选择进行了深入的比较研究,最后利用Matlab软件对这两种控制算法进行了仿真,从仿真结果可以看出直接功率控制在整流控制系统启动和负载突变等方面均优于双闭环直接电流控制。
The basic principles of the double closed-loop DC control and direct power control algorithm are analyzed in detials. The control structures of the two control algorithm and parameters are studied. Finally, the two kinds of algorithm is simulated by Matlab software. The simulated result shows that the direct power control is better than the double colsedloop DC control in start and load mutation of the commutation control system.
