The sufficient and necessary condition for holding the control system robust stability was analyzed in the presence of the process multiplicative uncertainties. 同时，对于实际生产过程中常见的被控过程乘性不确定性，分析了系统保持鲁棒稳定的充要条件。
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。
