摘要: 利用线性矩阵不等式(LMI)技术将增益调参的控制律设计转化为相应的LMI凸优化问题,结合 模糊控制和H方法,给出了一种基于LMI的模糊参数化的飞控系统增益调参控制器的 设计方法,该方法解决了传统增益调参设计中以经验设计的弊病,并保证了系统的全局 稳定性及鲁棒性能要求.将该方法应用于某型飞机模型上,仿真结果表明该设计方法简便有 效,且控制器鲁棒性较好.

Abstract: Linear matrix inequality(LMI), H-infinity  control and fuzzy logic control techniq ues were used for constructing such controller. With these techniques, the synth esis problem was reduced to a convex optimization related to LMI. A detailed pro cedure for developing a fuzzy logic gain scheduler over the full flight envelope was given in order to overcome the drawbacks of traditional design procedure ba sed on experience and ensure the global stability and robust performance of the flight control system. Simulation were constructed on an airplane model, the res ults indicates that the design method is feasible and robust to unmodeled dynami cs.
