非線性控制理論在有源濾波技術(shù)中的應(yīng)用
有源電力濾波器作為一種消除電網(wǎng)諧波的強(qiáng)有力的工具,正在蓬勃發(fā)展著,但是在實(shí)際應(yīng)用中還存在一些問題,同時(shí)向非線性控制理論提出了更高的要求。作者認(rèn)為,以下幾個(gè)方面是將來的研究重點(diǎn)。雖然目前將非線性控制理論應(yīng)用于有源電力濾波器剛剛處于初期階段,但有源電力濾波器與非線性控制理論的緊密結(jié)合將是一個(gè)具有生命力的發(fā)展方向。
對(duì)于反饋線性化,其控制器的建立需要系統(tǒng)的精確模型。雖然一方面, 可以通過設(shè)計(jì)魯棒非線性控制器來處理模型的不確定性;但在另一方面,如何建立適當(dāng)?shù)姆蔷€性模型來設(shè)計(jì)非線性控制器值得研究。必須針對(duì)有源濾波器本身的特點(diǎn)開展對(duì)系統(tǒng)建模和控制的研究。此外目前大部分研究是基于連續(xù)系統(tǒng)模型,因此有必要研究離散的非線性控制規(guī)律。反饋線性化方法通過抵消系統(tǒng)的非線性將原非線性系統(tǒng)線性化 ,進(jìn)而利用成熟的線性系統(tǒng)的設(shè)計(jì)方法。不過 ,并不是所有系統(tǒng)的非線性對(duì)系統(tǒng)的動(dòng)態(tài)特性的改善都具有相反作用。對(duì)特殊的非線性系統(tǒng)適當(dāng)?shù)睦梅蔷€性阻尼 ,相信可以得到更好的動(dòng)態(tài)性能。
自抗擾控制是一種不依賴于對(duì)象模型的非線性控制策略,魯棒性和適應(yīng)性都很強(qiáng),具有重大的理論意義和使用價(jià)值。此控制應(yīng)用于有源濾波器將有很廣泛的前景。
