摘要
研究了一类输入和状态都带有时滞的离散模糊双线性系统的非脆弱控制问题.在控制器存在加性摄动的情况下,通过并行分布补偿算法导出了非脆弱控制律的存在条件,使得闭环系统是渐近稳定的.利用线性矩阵不等式,提出了非脆弱模糊控制器的设计方法.数值仿真验证了所提方法的有效性.
The non-fragile control problem for a class of fuzzy bilinear systems with delay in both state and input was discussed.The objective was to design non-fragile state feedback controllers via the parallel distributed compensation(PDC) approach such that the closed-loop system was asymptotically stable.Some sufficient conditions for the existence of such non-fragile controllers were derived via the linear matrix inequality(LMI) approach and the design problem of the fuzzy controller was formulated as an LMI problem.The simulation example shows that the proposed approach was effective.
