【摘要】 提出了一种采用μ方法分析多变量飞控系统稳定裕度的新方法,并通过在回路中添加对角乘性摄动矩阵,建立了多变量系统鲁棒稳定裕度与经典的幅值-相角裕度之间的对应关系,给出了二者的对应关系图。最后,以某型飞机横侧向回路为例,验证了方法的有效性和优越性。更多还原

【Abstract】 A new method based on μ analysis is presented for evaluation of stability margin of a multivariable flight control system.The relationship between μ and classical stability margins of the multivariable system is established by introducing the multiple perturbation matrix at the input node,then an evaluation diagram of μ and gain-phase margin for stability margins analysis is given.Finally,the efficiency and advantage are demonstrated by the simulation.更多还原
