The value of dynamic stability lies in the definition of the kind of steady-state operation that the system can sustain. 动态稳定性的优劣取决于系统维持稳态工作的范围。
Then, the principle of virtual work is used to derivate the equilibrium condition of CM. 在以上基础上，应用虚功原理，推导出柔性机械稳态的条件。
Due to the idea of parameter-dependent Lyapunov stability, the obtained robust stability condition has less conservativeness than the one based on quadratic stability. 因为使用了参数依赖的李亚普诺夫稳定性思想，此鲁棒稳定条件比基于二次稳定概念的稳定条件的保守性更小。
