摘要
针对三相并联型有源滤波器,从能量守恒角度提出一种将周期离散控制技术和数字锁相环技术应用于直流侧电容电压控制的策略。设计了基于DSP-ARM的全数字控制系统,仿真和实验结果证明,设计的控制系统运算速度快,能跟踪和补偿频繁变化的负荷谐波。
A control algorithm based on DC capacitor voltage control and compensation on energy invariableness is proposed for three-phase shunt voltage APF.The period discrete control technique and digital phase-lock loop technique are applied to DC capacitor voltage control.A fully digital control system based on DSP and ARM is designed.Experiment results show that the system has high computing speed,so the frequently varied load harmonies can be traced and compensated.
