Macfarlane等提出的反标架方法(Reversed-Frame-Normalizing)是适用于多变量系统鲁棒性CAD的频域方法,这一方法是基于矩阵赋值函数的奇异值分解.本文在介绍这一方法的基础上,着重讨论反标架方法对系统鲁棒性设计的改进,并对该方法中分频段补偿器的设计提出了改进建议.通过数值例子说明这一方法较逆奈氏阵列法与特征轨迹法对系统鲁棒稳定性设计具有的优越性,也说明了这一方法在PC机上的可实现性.
Reversed-Frame-Normalizing proposed by Macfarlane et al. Is a frequency-domain method suitable for robust CAD of multivariable systems based on the singular value decomposition of matrix assignment functions.In this paper, Based on the discussion, the improvement of system robustness design with the anti-marking method is discussed, and some suggestions for improving the design of the sub-band compensator in this method are put forward.A numerical example is given to illustrate that this method is more effective than the inverse Naai’s array method and the feature locus The superiority of the method to robust stability design of the system also shows the feasibility of this method on a PC.
