摘要 研究了T-S模糊离散广义系统的鲁棒容许性问题.对于开环标称系统,基于严格线性矩阵不等式(LMI)给出了容许性判别条件.进而基于此条件并引入新的矩阵变量,得到严格线性矩阵不等式形式的鲁棒控制器设计方案.使得通过反馈控制,闭环系统在不确定性范围内是正则、因果、稳定的.最后通过算例仿真验证方法的有效性. The robust admissible conditions for T-S fuzzy discrete descriptor systems are investigated.Based on the new strict linear matrix inequalities(LMIs),the admissible conditions for open-loop nominal system are given.By introducing a new matrix variable,we established the sufficient conditions in terms of strict LMIs for robust controller design;the closed-loop system is regular,causal and stable for all parameter uncertainties.Numerical examples are provided to illustrate the effectiveness of the proposed design method.
