Abstract

In this paper a neural-net (NN) controller for tracking control of a manipulator is used. A manipulator is a nonlinear object which usually has unknown and changeable parameters. Dynamics equations of a rigid manipulator are presented. A NN controller is used for compensating manipulator's nonlinearities. The controller is realized in a form of a linear NN in the weights. The NN is learned by using backpropagation tuning. The presented control law and tuning algorithm are derived from the Lyapunov direct method. In this paper results of simulation and experiment are presented.
