Phatak, Makarand S and Keerthi, Sathiya S (1991) A Homotopy Method for Stabilization of Multivariable Systems with Structural Constraints on State Feedback.

Various structural Constraints on the state feedback gain matrix, K, used in the control of a multivariable dynamical system arise because of the way feedback is realized. Static output feedback, decentralized state feedback,simultaneously stabilizing state feedback for several operating points of a system, and two-controller feedback are some examples of control structure realizations which impost: constraints on K. We cast each of the problems in a general class of problems of stabilization of multivariable systems with such structural constraints into a problem of solving a system of equalities and inequalities which is then solved using a continuous realization of the gradient projection method and a barrier method under the homotopy framework. Our method is illustrated with two examples.
