摘要
随着电力电子技术和控制技术的飞速度发展,现代控制理论在有源电力滤波器中得到了广泛的应用。对现有的研究成果进行了综述,以便充分了解研究现状和发展趋势。概括了有源电力滤波器的基本工作原理、技术特点,详细论述了自适应控制、滑动模控制、反馈线性化解耦控制、无源性控制和智能控制在有源电力滤波器中的应用,给出了各种控制算法的特点及现有研究的不足。针对有源电力滤波器现有控制算法研究的缺点以及系统中不确定性较多的特点,需要应用鲁棒性较强,对模型依赖性不强的控制算法,如滑模控制、鲁棒控制、无源性控制和智能控制等,才能达到更好的控制效果。
With the fast development of power electronics and control theories,the modern control theories are applied into the APF(Active Power Filter)farther and wider.The recent researching achievement is overviewed to help the engineer grasp the status and the future in this field.The principles and characters of APFs are stated.The applications of modern control theories in APF,such as adaptive control,sliding mode control,feedback linearization de-coupling control,passivity based control and intelligent control,are discussed in detail.Every control strategies have their own merits and demerits.For the disadvantages of the current researches,the control methods that is more robust and with little dependence on the model of the system are better to solve the uncertainty and stability of the APFs.They are sliding mode control,robust control,passivity based control and intelligent control and so forth.This project is supported by Guangdong Key Scientific Fund(A1050202)and National Key Re-search Fund(1998020308).
