非線性控制理論在有源濾波技術(shù)中的應(yīng)用

摘要：　　綜述了非線性控制理論在有源電力濾波器中的應(yīng)用，分別對反饋線性化方法、非線性變結(jié)構(gòu)控制、非線性無源控制、非線性自適應(yīng)控制、非線性 魯棒控制以及自抗擾控制在有源濾波技術(shù)中的應(yīng)用加以討論，提出了仍然存在的技術(shù)難題，并展望了有價值的研究方向和應(yīng)用前景。 敘詞：非線性控制 有源濾波器 諧波 Abstract：　　This paper provides an overview of the application of the nonlinear control theory in active power filter (APF), pointing out the existing problems with an emphasis of the potential application of the nonlinear control in the filed. Several main modern control methods, including feedback linearization method, nonlinear sliding mode control, nonlinear passivity-based method, nonlinear adaptive control, nonlinear　 robust control, and the auto-disturbances rejection control, have been discussed.
