摘要 研究了连续TS模糊控制系统稳定性判别条件与平衡点稳定吸引域估计方法的进一点改进。首先基于模糊李亚普诺夫函数,给出了连续TS模糊控制系统的稳定性充分条件;该条件更一步减小了判别的保守性。其次基于模糊李亚普诺夫函数,进一步改进了连续TS模糊控制系统渐近稳定平衡点稳定吸引域的估计方法;该方法简单实用,最大限度地估计稳定吸引域大小。实例验证了该方法的有效性和实用性。 This paper deaIs with stabiIity anaIysis and controI design probIems for continuous-time Takagi-Sugeno （TS） fuzzy sys-tems.FirstIy,based on LMIs,sufficient stabiIity and stabiIization conditions are given which further reduce the conservativeness. SecondIy,a new approach to find an inner estimate of the domain of attraction （DA） is presented via LMIs,which is simpIe and practicaI and tries the best to enIarge the domain of attraction.
