The value of dynamic stability lies in the definition of the kind of steady-state operation that the system can sustain. 動態穩定性的優劣取決于系統維持穩態工作的范圍。
Then, the principle of virtual work is used to derivate the equilibrium condition of CM. 在以上基礎上，應用虛功原理，推導出柔性機械穩態的條件。
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。
