摘要
研究一类能够用离散动态模糊模型描述的复杂非线性系统的模糊控制稳定性问题·首先设计出PDC模糊控制器· 然后利用区间系统理论 ,在带扰动系统二次稳定意义下给出了闭环系统渐近稳定的两个充分条件 ,并且后一稳定性条件被转化为线性矩阵不等式可解性问题· 仿真结果证明了此方法的有效性·
The stability problem of a class of complex nonlinear systems represented by a discrete-time dynamical fuzzy model was studied. First,a PDC fuzzy controller was designed to stabilize the model. Then, based on interval theory, two sufficient conditions for the asymptotic stability of the fuzzy system were given in the sense of the quadratic stability of the uncertain linear system. The latter condition was converted to the solvability of a linear matrix inequality.
