Abstract
A nonlinear H∞ disturbance attenuation based solution of adaptive control for nonlinear systems with unknown (certain or uncertain) parameters is put forward. It is shown that the adaptive control law can be obtained by solving a revised Hamilton-Jacobi-Isaacs inequality (or equality) directly when an estimator can be obtained satisfying the presented conditions. The asymptotic stability of the closed loop system can be guaranteed when the estimate of the uncertain parameter converges to the true value or the stability when the estimate is bounded
