Abstract
A general suboptimal control problem is posed and an expression for a suboptimal controller is derived solving the saddle point conditions. An expression for a state feedback suboptimal controller can be derived by solving a dynamic Riccati equation. Then, an expression for a suboptimal output feedback controller is developed in a general case via the solution of two dynamic Riccati equations.Keywords
