Adaptive Passivation of a Magnetic Levitator System Using Time-Varying Gains 1

Abstract In this paper, an adaptive controller with time-varying gains is proposed to solve the problem of controlling a nonlinear model of a magnetic levitation system. The controller is based on adaptive passivity concepts developed for a class of nonlinear systems. The methodology proved to have a good performance as compared with the constant adaptive gains case.
