| 摘 要： | 在三相单位功率因数整流器中，实际电流能否跟踪参考电流将影响整个系统的控制性能，文章指出了一种适合数字化控制的电流控制方法，以李雅普诺夫直接法为基础，引入了反馈增益，用来抑制系统参数变化的影响，并比较了变反馈增益和定反馈增益的效果。仿真结果表明了该方法将有效地克服系统参数变化对控制性能的不利影响。

| Abstract: | Whether actual current can track reference current well will affect the control performance of three phase rectifier with unity power factor.A current control method adjusted to digital control is proposed in this paper,which is based on Lyapunov's direct method,importing feedback gain to restrain influence of system parameter variation,and the effect of varying feedback gain and unvarying feedback gain are compared.Simulation results show that this method will overcome the disadvantageous effect resulted from parameter variation. |
