【摘要】 研究了离散时滞T-S模糊系统基于模糊Lyapunov-Krasovskii函数的H∞控制问题.通过构造离散型模糊Lyapunov-Krasovskii函数,首先给出了一个使得T-S模糊系统渐近稳定的充分条件,然后给出了相应的H∞控制器的设计方法,该设计方法保证了模糊闭环系统内部渐近稳定并满足从干扰输入到控制输出的H∞范数界约束,且具有较少的保守性.最后通过仿真实例,验证了该方法的有效性.更多还原

【Abstract】 The H∞ control problem of discrete T-S fuzzy systems with time-delay are studied via fuzzy Lyapunov-Krasovskii function.With fuzzy Lyapunov-Krasovskii function,a new sufficient condition which guarantees T-S fuzzy systems are asymptotically stable,is proposed.Then the design procedures for H∞ controller are given,which guarantee that the closed-loop system is asymptotically stable,and the effect of the disturbance input on the controlled output is reduced to a prescribed level.The simulation result shows that the proposed method is effective.更多还原
