VIENNA整流器PI控制器参数设计方法
Parameter Design Method of PI Controller for VIENNA Rectifier
摘要
Abstract
For parameter optimization of the PI controller for the VIENNA rectifier,the use of correcting the system into a typical structure needs to do approximate processing,which will cause some errors for the whole settings, and sometimes the system will not be simply adjusted to the typical structure.By setting the anticipant open loop cut-off frequency and phase margin of current loop and voltage loop,the controller parameters could be calculated analytically, which means the disadvantage could be avoided.At the same time,it could also inverse-calculate the cut-off frequency and phase margin to evaluate the system performance of the given PI parameters. The method established the relationship among the system frequency domain parameters,PI parameters and system performance in time domain, which had made the tuning target intuitive and clear. With clear physical meaning of the parameters,the proposed strategy could be achieved easily. Finally,the simulations and experimental analysis verify the correctness and the effectiveness of the proposed method.关键词
