Abstract :
An approach to the solution of the adaptive control for nonlinear systems with unknown (certain or uncertain) parameters is presented by using the theory of nonlinear H∞ disturbance attenuation control. It is shown that the adaptive control law is related to the existence of the solution of a new form of Hamilton-Jacobi-Isaacs inequality (or equality). The asymptotical stability of the closed loop system can be guaranteed when the estimators of the uncertain parameters converge to the true value
