A generalized linear-quadratic optimal control problem for systems with delay admits a state feedback form solution having some desirable robustness properties, locating closed-loop poles to be a specified region and being realized by solving a finite-dimensional Riccati equation.
We derive closed-form solutions for the linear-quadratic (LQ) optimal control problem subject to integral quadratic constraints. The optimal control is a non-linear function of the current state and the initial state. Furthermore, the optimal control is easily calculated by solving an unconstrained
