讨论了状态空间形式下Ｔａｋａｇｉ和Ｓｕｇｅｎｏ提出的一类模糊系统的稳定性，利用矩阵范数和矩阵分析理论给出了判定该类系统稳定的新的充分条件。在此基础上分析了国产某飞机在地面滑行时纵向短周期运动的稳定性，比以往结论更加有效。
The stability of a class of fuzzy systems proposed by Takagi and Sugeno in state space is discussed. The new sufficient conditions for judging the stability of the system are given by using the matrix norm and matrix analysis theory. On this basis, the stability of a longitudinal short-period motion of a domestic aircraft when it glides over the ground is analyzed, which is more effective than the previous conclusions.
