A diesign method of a high gain feedback control system.

A design method is proposed which is useful for constructing a high gain feedback control system. The total system derived by this method is considered to be two subsystems : a fast-mode system and a slow-mode system. The pole assignment of these subsystems is arbitrary. The fast-mode system can be chosen to be of higher order than the number of the inputs. The method can be applied to a servo system. It is also investigated from the viewpoint of its effectiveness in disturbance and parameter variations.
