摘　　要：运用线性矩阵不等式(LM I)的H∞控制理论,将舰载机纵向着舰导引系统的S ISO性能要求转化为H∞控制广义模型权函数的选择,设计出H∞输出反馈控制器。以某型舰载机着舰过程进行仿真验证,结果表明,采用H∞控制的着舰导引系统具有良好的着舰下滑轨迹跟踪能力。H∞ control theory, based on linear matrix inequalities （LMI）, is used to the design of the longitudinal carrier landing system for carrier aircraft. The SISO specification of the longitudinal carrier landing system was translated into the weighting functions of the generalized model for H∞ synthesis. The resulting H∞ output feedback controller was presented. The simulation results indicate that the designed carrier landing system can satisfy the mission performance requirements.
