摘　　要：利用模糊模型处理了非线性离散不确定系统的稳定性问题,针对一类离散不确定T-S模糊系统,使用一种新的T-S模糊系统放宽的二次稳定方法,研究并设计了T-S模糊离散控制器,在此基础上利用线性矩阵不等式给出了控制器的算法。最后,通过仿真示例说明了该方法的可行性。This paper addressed the issue of the use of fuzzy model for nonlinear discrete uncertain system stability.Against a kind of uncertain discrete T-S fuzzy system,its controller was studied and designed with a newT-S fuzzy system relaxed quadratic stabilization methods.On this basis,the algorithm of the discrete T-S fuzzy controller was derived by linear matrix inequalities.Finally,its feasibility was illustrated by simulation examples.
