Analytic approach to quadratic control with prescribed relative stability
HENG ZHANG, Song Shu · International Journal of Control · 1988
A new approach to quadratic control with prescribed relative stability is presented using a discrete-type Riccati equation. The algorithm for determining the feedback matrix is an analytic design procedure. Quadratic weights, corresponding to such a feedback control, are explicitly and simply obtained by derived formulae. Examples are used to illustrate the efficiency of the proposed approach.
