Abstract

A new approach to the design of the central output H∞-controller was proposed. It is based on defining the controller’s structure in compliance with the principle of division which is applicable equally to the standard nondegenerate problem and the degenerate problems such as the singular filtration problem (no measurement noise) and singular control problem (no component containing control in the controlled output). Within the framework of the given approach, the general problem of designing the output controller was shown to fall down into two special design problems—under full information and full control. For the degenerate problem, the dimension of the central controller at that drops, and the solution itself is coordinated with the problem of H2-optimization. An example illustrating solution of the singular filtration problem was presented, and the results obtained were analyzed.
