摘要
本文借助变形Riccati方程解的特殊性质,提出了一种设计多变量控制系统的方法,其闭环系统的极点位于理想区域,且在某一性能指标意义下是最优的.同时,还能保证这个系统在某一控制信号失效时,仍能稳定工作,即具有稳定鲁棒性.文中给出的设计实例,证明了本文提出的方法的优越性.
With the aid of the solution of a deformed Riccati equation,a new design proce-dure for a multivariable feedbck control-system is presented in this paper.By usingthis procedure,all the poles of a closed-loop system can be located in the desired re-gion,and the designed system can be optimal in the sense of satisfying certain per-formance indexes.Meanwhile,the system still remains stable in the presence of somefailures in the feedback loop,i.e.,it possesses sound stability.Finally,the paper pro-vides a numerical example and shows its validity.
