In this paper we extend to completely general nonlinear systems the result stating that the H{sub {infinity}} suboptimal control problem is solved if and only if the corresponding Hamilton-Jacobi-Isaacs (HJI) equation has a nonnegative (super)solution. This is well known for linear systems, using the Riccati equation instead of the HJI equation. We do this using the theory of differential games and viscosity solutions.
