A design scheme for incomplete state or output feedback with applications to boiler and power system control

Bengtsson, Gunnar and Lindahl, Sture LU (1974) In Automatica 10(1). p.15-30
Abstract
The problem of designing a linear feedback when all state variables are not available is discussed. The design scheme is based on computation of a complete state feedback and a reduction to a specified structure. The reduction is made by approximation of the eigenspace corresponding to a set of dominant eigenvalues. The method consists of successive choices of weightings on this space. The method is applied to the control of a boiler and a three-machine power system. In the power system case the complete state feedback can be replaced by local output feedback without significant decrease in performance.

The examples indicate that the proposed method is a realistic design method for multivariable systems.
