| 摘 要： | 运用非线性模糊滑模变结构控制理论，提出了对并联型电能质量调节器进行模糊滑模变结构控制的设计方法，该控制方法能改善系统电能质量的调节，有效地补偿负荷侧谐波电流，无功功率和负序电流，仿真结果表明，该控制规律与常规PI综合控制引比具有较强的实时性和鲁棒性，并能有效改善系统的暂态稳定性。

| Abstract: | Applying sliding mode based nonlinear fuzzy variable structure control (VSC) theory, a design method of fuzzy slide mode based VSC control for shunt unified power quality conditioner is proposed. This control principle can improve the control of power quality and effectively compensate the harmonic currents at load side, reactive power and negative sequence current. Simulation results show that comparing with conventional PI composite control, the presented method possesses better real-time feature, robustness and good dynamic compensation character, otherwise, it can effectively improve the transient stability of power system. |
