Adaptive Levitation Control Based on Feedback Linearization

Abstract:

This study mainly addresses the adaptive control for the levitation system in presence of mass variation. Firstly, considering the nonlinear of levitation system, the feedback linearization is applied to achieve the global stabilization. Due to the additions of luggage and passengers, the variation of mass degrades the dynamic performance of levitation system, it is necessary to estimate and cancel the effect of mass variation. So an algorithm to estimate the mass of levitation system is proposed and integrated to adjust the parameters on line. The results of simulations show that excellent closed-loop performance is provided in the presence of mass variation.
