An approach to nonlinear discrete-time H/sub ∞/-control

Following recent works proposed in the continuous-time context concerning the nonlinear equivalent of the H/sub /spl infin//-control problem and its connection with game theory and Isaacs equation, the present paper studies the same problem in the discrete-time contest. A digital static feedback law achieving closed-loop stability and disturbance attenuation is designed under full information assumption by making use of an observer.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
