Abstract :
A neural network based method has been proposed for control system´s gains tuning, but the network training is time consuming. Thus, several improvements of the classical backpropagation algorithm are investigated in order to speed-up the learning process. They are theoretically analyzed, and their effectiveness is confirmed with the application to the control of a nonlinear model of direct-drive two-axis robot manipulator. It is clarified that the convergence efficiency of the optimization process can be drastically increased by those improvements, resulting in a faster training of the network
