摘要：

This paper is concerned with the problem of designing tracking controllers for magnetic levitation systems. Using the input-state feedback linearization technique of nonlinear systems, and considering the structure of the linearizing transformation in the case of magnetic levitation systems, a linear reduced-order observer to estimate the states of the input-state linearization is designed. Then, from the estimates obtained by the observer and using integral control, a tracking control law for the input-state linearization is designed and, finally, a tracking controller for the magnetic levitation system is derived.
