FEEDBACK CONTROL OF CLOSELY SPACED MODE SYSTEM

This paper studies closely spaced mode system using feedback control law designed for repeated mode system. The damping factors of close loop system is analysised in three cases, the repeated mode system's feedback controller used in closely spaced mode system, in closely spaced mode system with parameter perturbation, in partly controllable closely spaced mode system.It is shown that with right coordinate transformation in the cases, the error of th...
