摘　　要：有源电力滤波器(ActivePowerFilter,APF)是补偿电力系统谐波及无功功率的重要装置,其控制的实时性和准确性是实现有效补偿的一个关键。数字信号处理器(DigitalSignalProcessor,DSP)是一种实时计算速度快、精度高的控制器,能满足APF各种控制方案快速响应的要求,并可有效提高控制系统的实时性和准确性。文章介绍了基于DSP的空间矢量调制、滞环电流控制、单周控制、滑模控制、无差拍控制、重复控制、预测控制、模糊控制以及人工神经网络控制这几种APF控制方案的基本原理,指出了它们各自的优缺点。Active power filter （APF） is an important equipment to compensate harmonic and reactive currents in power systems and the key problem of the effective compensation lies in the real-time and accurate control. Because digital signal processor （DSP） possesses the advantage of high operation speed and can provide accurate calculation results, so it can meet such requirement of various APF control schemes as real-time and accurate calculation and fast response, and also can effectively improve the accuracy of control system. The authors present fundamental principles of several APF control schemes based on DSP such as space vector modulation, hysteresis current control, monocyclic control, slide mode control, dead beat control, repetitive control, predictive control and ANN based control, and the respective merit and demeritof these control method are pointed out.
