Study on Multi-frequency Cascade Passivity-based Control for the Series Converter of Unified Power Quality Conditioner
摘要
Abstract
Mathematical model of the series converter ofunified power quality conditioner (UPQC) is a high-order model.In order to improve the dynamic and static performance of the high-order system in frequency domain,a control scheme called multi-frequency cascade passivity-based control (PBC) is presented.Firstly,Fourier transform technique is applied to establish the multi-frequency DC model of the series converter,then the high-order system can be considered as a cascade low-order system onthe selected frequency model,anda novel PBC controller is designed based the cascade model.Theoretical analysis shows that it can not only realize flexible control for the series converter on frequency domain,but also achieve zero steady-state error control at selected frequency with inaccurate model parameters,and it can overcome the shortcoming that traditional PBC can hardly achieve zero steady-state error with inaccurate model parameters.Finally,experimental results verifythat the proposed control strategy is feasible.关键词
