T-S模糊时滞系统分段鲁棒耗散控制器的设计

The piecewise fuzzy robust dissipative controller design of T-S system with time delays

用分段模糊Lyapunov函数方法和线性矩阵不等式工具研究了时滞不确定T-S模糊系统的鲁棒耗散控制器的设计问题。设计出的控制器能够保证对于T-S模糊系统中所有的参数不确定性和时滞,闭环系统都是稳定的且满足给定的耗散性能指标。相比用公共Lyapunov函数方法,得出的结论具有更小的保守性。

The piecewise fuzzy robust dissipative controller of T-S system with time delays is designed with the method of piecewise fuzzy Lyapunov function and linear matrix inequality. The proposed controller can guarantee that for all admissible uncertainties, the resultant closed-loop systems are stable and satisfy dissipative performance. The proposed result is less conservative than the approaches with common Lyapunov function.
