摘　　要：针对三相并联型有源电力滤波器的仿射非线性模型,通过分析得出该模型满足状态反馈的条件,基于微分几何提出了一种基于状态反馈精确线性化的非线性控制策略,设计了非线性控制器,实现了对有源电力滤波器的输出控制。仿真结果表明,该非线性控制器的各项性能指标均良好,验证了所提出的控制方案性能优越。An affine nonlinear model of three-phase shunt Active Power Filter(APF)is built by the state-space average modeling method and it is theoretically verified that the model satisfies the conditions of state feedback exact linearization.Based on the differential geometry,the nonlinear controller is designed to implement the decoupled control of APF.The proposed control scheme solves the nonlinearity problem of the model system completely in the whole operating range,and enhances the dynamic responses of the system.The simulation results based on the detection and control method are given,which shows the proposed nonlinear control strategy is validity and feasibility.
