OPTIMAL H(INFINITY)-STATE FEEDBACK-CONTROL FOR CONTINUOUS-TIME LINEAR-SYSTEMS
Journal Of Optimization Theory And Applications. Plenum Publ Corp, v. 82, n. 2, n. 343, n. 359, 1994.
This paper proposes a convex programming method to achieve optimal H(infinity)-state feedback control for continuous-time linear systems. State space conditions, formulated in an appropriate parameter space, define a convex set containing all the stabilizing control gains that guarantee an upper bound on the H(infinity)-norm of the closed-loop transfer function. An optimization problem is then proposed, in order to minimize this upper bound over the previous convex set, furnishing the optimal H(infinity)-control gain as its optimal solution. A limiting bound for the optimum H(infinity)-norm can easily be calculated, and the proposed method will achieve minimum attenuation whenever a feasible state feedback controller exists. Generalizations to decentralized and output feedback control are also investigated. Numerical examples illustrate the theory.822343359
