Abstract :
In this paper we propose an adaptive NN control design to compensate for the pivot nonlinearity. To capture the time-varying uncertainties and nonlinearity, the adaptive tuning scheme is employed for NN weights, receptive center and width. The simulation and experimental results shows the effectiveness of the proposed scheme.
