Abstract :
It is difficult to solve the discrete regulator equations arising from the discrete-time nonlinear output regulation problem. The application of output regulation problem to mechanical systems is of interest especially for an under-actuated system - pendubot system. In this paper, a digital controller for the pendubot system is designed by using approximate output regulation approach. The simulation shows that the control law performs much better than the conventional linear control law.
