| 摘 要： | 针对应用公共Lyapunov函数方法和模糊Lyapunov函数方法判定离散T-S模糊控制系统稳定性存在的保守性和难度，在定义离散型分段模糊Lyapunov函数的基础上，应用并行分布补偿方法（PDC）设计出使模糊系统全局渐近稳定的拉制器，并提出和证明了一个新的判定用环离散T-S模糊系统稳定的充分条件，该条件降低了上述方法的保守性和难度。通过一个仿真例子验证了方法的有效性。

| Abstract: | For the conservatism and difficulty of checking the stability of discrete T-S fuzzy control system with the common Lyapunov function approach and the fuzzy Lyapunov function approach, a fuzzy controller was designed to acquire globally asymptotical stability for discrete fuzzy system with the method of parallel distributed compensation (PDC) after the definition of a piecewise fuzzy Lyapunov function. Then a new sufficient condition to check the stability of closed-loop discrete T-S fuzzy system was proposed and proved. This condition is less conservative and difficult than above approaches. At last, a simulation example shows that the approach is effective. |
