The sufficient and necessary condition for holding the control system robust stability was analyzed in the presence of the process multiplicative uncertainties. 同時，對于實際生產過程中常見的被控過程乘性不確定性，分析了系統保持魯棒穩定的充要條件。
Due to the idea of parameter-dependent Lyapunov stability, the obtained robust stability condition has less conservativeness than the one based on quadratic stability. 因為使用了參數依賴的李亞普諾夫穩定性思想，此魯棒穩定條件比基于二次穩定概念的穩定條件的保守性更小。
