Output Feedback Control of Servodamper System

Abstract

This paper presents a systematic design of servodamper systems from a point of view of output feedback control. Firstly, by using a parameter optimization technique, the output feedback control law is derived. In the case of incomplete feedback problems, however, the instability of the system must be considered in contrast to the optimal control system. Secondly, this paper presents a new concept of "the best performance point", which minimizes the mean square value of a state. Thirdly, in accordance with the best performance point, the determination of the output control law o f a servodamper system is demonstrated and the resulting system is compared with the optimal control system. The experiment of the servodamper system subject to the application of the output feedback control law is also derived.
