摘要

提出了一种基于二次性能指标的简单自适应控制算法,通过采用滞环电流控制产生了脉宽调制的开关信号,设计了并联型有源滤波器直流电压控制器。仿真结果表明,与常规的比例–积分控制相比,对并联型有源滤波器直流电压采用简单自适应控制可获得更好的动态性能,且负载变化时的鲁棒性更好。

Abstract:

The authors propose an improved quadratic performance index based simple adaptive control (SAC) algorithm and apply it to the design of a DC voltage controller for shunt active power filter, in which the pulse-width- modulation (PWM) switching signal is generated by hysteresis current control. Simulation results show that the dynamic performance of simple adaptive controller is better than conventional proportional integral (PI) controller and simple adaptive controller possesses better robustness while load varies.

Keywords: shunt active power filter   simple adaptive control (SAC)   quadratic performance index   DC voltage   mathematical model
