Uncertainties inevitably and time-delay quite widely exist in all kinds of physi-cal, industrial and engineering systems, and they have a significant e?ect on systemperformance and make the closed-loop system unstable. It is di?cult for the moderncontrol theory, which is based on the exact mathematical model, to make control sys-tems satisfy the desired performance, therefor it is necessary to study. In this thesis,the problem of robust H_∞based on RBF neural network is studied for uncertain non-linear syst...
