摘　　要：有源滤波器能否按其工作原理实现预期的谐波抑制效果,在很大程度上还依赖于电流跟踪控制算法的优劣。该文以一种新型注入式混合有源滤波器为例,结合传统滞环控制算法响应速度快和比例谐振积分控制算法无稳态误差的优点,提出采用复合型控制作为该混合有源滤波器的电流跟踪控制算法。通过相关的仿真、实验结果,从跟踪速度、控制精度、开关谐波含量和开关器件损耗4个方面,将复合型控制算法与传统滞环控制算法及单一的比例谐振积分控制算法进行比较研究。相关分析方法和所得结论可为其他类型的混合有源滤波器的电流跟踪控制算法研究提供借鉴。Whether a hybrid active power filter results in desirable harmonic eliminating effect, mainly depends on current tracking performance of the controller. By modeling a new injection type hybrid active power filter, this paper proposes a new synthesis control method which combines the speedy performance of traditional hysteretic control with the zero steady state error of proportional-resonance integrators. With this new control algorithm, this paper takes some simulations and experiments to verify its effects, and compares with traditional hysteretic control and the one just using proportional-resonance integrators in the aspects of tracking speed, control precision, harmonic components and the energy loss of switching. The method for theoretical analysis and relative conclusion presented in this paper can be used as references to design current tracking controller for other type hybrid active power filter.
