摘要
模型预测控制(model predictive control,MPC)是一种应用于变流器控制领域的新型控制算法。传统的基于PI调节器的指令次谐波补偿方法,控制结构复杂,执行过程繁琐。文中将MPC用于并联型有源滤波器(shunt active power filter,SAPF)谐波电流指令的跟踪控制,该策略可以在三相静止坐标系下直接执行,省略了锁相环和旋转坐标变换,可实现各次谐波的统一控制,控制结构简单。此外,还提出基于谐振型带通滤波器的谐波检测方法,该方法可检测任意次谐波电流,提高了谐波补偿的灵活性。仿真和物理实验结果验证了所提策略能够取得良好的谐波补偿效果。
Model predictive control (MPC) is a novel control method for the field of converter control. For traditional selective harmonic compensation method based PI regulator, its control structure and execution process are both complicated. MPC is used to achieve the tracking of reference current for shunt active power filter (SAPF), which can implement in three -phase stationary frame, remove PLL and rotating coordinate transformation and control every harmonic current. Furthermore, resonant type band pass filter is presented to detect random harmonic current, which improves the flexibility of the harmonic compensation. Simulation and experiment results demonstrate that the proposed control strategy can achieve a good harmonic compensation effect.
