Abstract: A quantitative analysis method of redundant hardwares in multivariable control sys-tems is proposed,with which the designers can know which component failures in the system will make the system unstable and under which component failures the system remains stable with some stability margin by carefolly adjusting some parameters in the design stage,so that it offers an important basis for the setting of redundant hardwares in the multivariable control sys-tems.A large flexible space station is taken as an example to illustrate the suggested method.

Key words: multivariable control, failure analysis, redundant components
