摘要：

This paper presents a new Loop Transfer Recovery procedure which recovers a robustness property at plants inputs to a specified degree. It is pointed out that stability of a controller is a necessary condition for the LTR procedure. A weighted difference between the open loop transfer function of a state feedback system by a LQ regulator and that of an output feedback system by a LQ regulator with an observer is estimated quantitatively by an H(infinity) norm. A design problem of full/minimal order observers for which the norm is less than a specified value is proposed. This problem is reduced to an H(infinity) optimal control problem with state feedback. A relation between this method and LQG/LTR method is examined.
