:Relationship between Structures of Feedback Compensator and Dynamics of the Controlled System

概要

One of the major problems in designing the magnetic bearing control system is that the two rotational motions of the rotor interact on each other by gyroscopic effects. Two control methods are presented for the gyroscopic coupled system. The system compensated by one method, which is called optimal regulator system, has an antisymmetric cross feedback compensator. The system compensated by the other method, which is called independently controlled system, has no cross feedback compensator. There are many differences in dynamics between the two compensated systems. The differences are explained clearly by representing the system dynamics in complex variable form. And it is shown that the optimal regulator system is superior to the independently controlled system in point of transient response characteristics.
