  6. Abstract : the physical significances of the reaching law parameters and the qualitative relationships among them in variable structure control ( vsc ) are analyzed. according to the relationships, a reaching law control method is put forward based on fuzzy rules. to improve control quality, the reaching law parameters are selected by fuzzy rules. the control scheme presented in this paper not only preserves the advantages of traditional reaching law control, that is, insensitivity to any variation and perturbation of the plant parameters, but also possesses the adaptation to control quality of variable structure control systems. the simulation results show the chattering in vsc systems is highly reduced

    文摘:分析了變結構控制設計方法中趨近律參數的物理意義及參數之間的定性關系,根據這些參數的定性和不精確關系,提出了基於模糊規則的趨近律控制? ?模糊趨近律控制,即用模糊規則來選擇趨近律的參數,以達到改善品質控制的目的.模擬結果表明,筆者給出的方法既保留了傳統趨近律方法所具有的較強魯棒性優點,又使控制系統的品質控制具有較強的自適應性,同時還比傳統趨近律方法更有效地削弱變結構控制系統中固有的顫振
