Based on the Kleinman iterative algorithm, the online adaptive controller design problem of a class of nonlinear systems is studied in this paper. The neural network linear differential inclusion technique is firstly used to model the studied nonlinear systems. Then, without considering the dynamic parameter matrix of the system, the Riccati equation is solved by means of the Kleinman iterative algorithm. Subsequently, the adaptive controller is designed and the convergence of the algorithm is proved. Finally, a numerical simulation example is given to illustrate the feasibility of the algorithm.
