用改进的奇异摄动法设计飞行控制系统

Design of Flight Control System Using Improved Singular Perturbation Method

本文应用Ｂ．Ｐｏｒｔｅｒ等提出的跟踪系统控制律设计的奇异摄动法设计飞行控制系统；引入特征结构配置进行量测矩阵Ｍ的选择；应用复数域内的奇异值分解方法计算矩阵的零空间以选取闭环系统特征向量；最后通过计算逆回差矩阵的最小奇异值之量分析了闭环系统的鲁律性．

The authors start from the first author,s 1991 Ph.D thesis [91 and the 1981 paper of Porter et al[31 andthen reduce greatly the deficiencics still existing in the two papers aest mentioned.The result is an improved singular permrbation theory that can be used to get better design of flight control system(FCS).Although Ref.[91 is quite good in many respects,its serious deficienCy is that System robustness isunsatisfactory. Porter's method is deficient when the matrix [Cd is deficient, because then mcasurcmcn...
