摘　　要：为改进有源电力滤波器APF的电网电流补偿效果,基于APF的端口受控哈密顿(PCHD)数学模型,采用互联和阻尼配置无源控制(IDA-PBC)方法,设计了通过模糊控制实现注入阻尼在线调整的无源混合控制器。同时,为提高APF的直流侧电压控制能力,采用自适应模糊PI控制器,实现比例系数与积分系数的在线调整。利用所提出的控制器,可有效补偿电网电流,抑制负载电流谐波,使电网电流为近似正弦波;同时,获得更好的直流电压动静态性能。在Matlab/Simulink仿真平台上搭建APF自适应模糊无源混合控制器的仿真模型,对APF的谐波补偿性能进行了仿真实验研究。仿真结果表明所提出的自适应模糊无源混合控制策略是可行的。The passivity based hybrid controller which can adjust the damping injection online through fuzzy control theory is designed based on the Port Controlled Hamiltonian with Dissipation（PCHD） mathematical model of Active Power Filter（APF） and through the method of Interconnection and Damping Assignment Passivity Based Control（IDA-PBC） to improve the current compensation effect of APF. While self-adaptive fuzzy PI control method is used in order to adjust the proportional and integral coefficient online to improve the DC side voltage control performance of APF. Using the controller proposed, the source current can be compensated and the load harmonic current can be suppressed effectively, which makes the power supply current sinusoidal and gets a better dynamic and static performance of DC voltage. The simulation models of APF and the self-adaptive fuzzy-passivity based hybrid control system are built based on Matlab/Simulink. The harmonic compensation performance of APF is simulated and analyzed. The simulation results show that the self-adaptive fuzzy-passivity based hybrid control strategy proposed is feasible.
