nonconvex necessary and sufficient conditions
Standard \(H_\infty\)-optimal control problem with a quadratic performance functional of the general form
The paper gives nonconvex necessary and sufficient conditions and convex sufficient conditions for the existence of a solution to the standard \(H_\infty\)-optimization problem with a quadratic function of the general form.NEWLINENEWLINENEWLINEThese conditions are expressed via frequency characteristics and via the coefficients of the systems in the state space.
