Simultaneous Stabilizing Controller with Robust Servo Characteristic

抄録

There exist a viewpoint that problem of simultaneous stabilizing two plants using a common controller is equivalent to stabilizing a single plant using a strongly stabilizing controller. However, the strongly stabilizing controllers cannot have a pole at the origin. It is said that the simultaneous stabilizing controller has bad robust servo characteristic. The purpose of this paper is to clarity the relation between the simultaneous stabilization and strong stabilization, and present the class of simultaneous stabilizable plants which can simultaneous stabilizing by simultaneous stabilizing controllers with robust servo characteristic.
