有源电力滤波器滑模-无源控制策略研究
摘要:为了提高有源电力滤波器(active power filter,APF)的补偿性能和谐波抑制能力,提出电压外环采用趋近律滑模控制(sliding mode control,SMC)、电流内环采用无源控制(passivity based control,PBC)的SMC-PBC策略。与比例积分(proportion integration,PI)和PBC相结合的PI-PBC策略、PI和滞环电流控制(hysteresis current control,HCC)相结合的PI-HCC策略相比,SMC-PBC策略可以使APF在负载改变时补偿后的电网电流更接近于正弦波。通过MATLAB/Simulink实验平台进行仿真验证,结果表明SMC-PBC策略有效可行。
Abstract:In order to improve the compensation performance and harmonic suppression ability of active power filter (APF), the SMC-PBC strategy with reaching law sliding mode control (SMC) in voltage outer loop and passivity based control (PBC) in current inner loop was proposed. Compared with the PI-PBC strategy combining proportion integration (PI) and PBC, the PI-HCC strategy combining PI and hysteresis current control (HCC), SMC-PBC strategy can make the compensated current of APF closer to sine wave when load changes. The simulation results of MATLAB/Simulink experimental platform show that the SMC-PBC strategy is effective and feasible.
