摘　　要：建立了飞控系统的模糊模型 ,通过采用线性矩阵不等式LMI(LinearMatrixInequality)得到了一种既可保证模糊系统全局渐近稳定又能将闭环极点配置在期望区域的模糊控制系统的设计方法 .对用该方法设计的纵向模糊飞控系统进行了仿真和鲁棒性验证 .仿真结果表明所设计系统满足既定的性能指标要求且具有较好的鲁棒性 .A fuzzy flight control system model was established. Using linear matrix inequality (LMI), a design method was obtained, which guarantees that the fuzzy system has global asymptotic stability and the poles were assigned to anticipant areas. The numerical simulations of a fuzzy flight control system designed by this method show that the system possesses satisfactory performances and good robustness.
