4-Riccati approach to optimal controller design problem

The necessity of introducing the intellectual control systems is motivated. A possibility to eliminate the uncertainties in the problem to control solving the algebraic Riccati equations, is established. Each equation corresponds to one of four types of possible uncertainties. Disclosure of uncertainties while designing the robust optimal controller on the basis of Riccati equations solution, is illustrated on an example of the mixed Н₂/Н_∞ control problem.
