Output feedback control of a mechanical system using magnetic levitation.
This paper presents an application of a nonlinear magnetic levitation system to the problem of efficient active control of mass-spring-damper mechanical systems. An output feedback control scheme is proposed for reference position trajectory tracking tasks on the flexible mechanical system. The electromagnetically actuated system is shown to be a differentially flat nonlinear system. An extende...
متن کاملExplicit nonlinear predictive control for a magnetic levitation system
The paper presents a methodology for the construction of an explicit nonlinear control law via approximation of the nonlinear constrained finitetime optimal control (CFTOC). This is achieved through an approximate mapping of a general nonlinear system in a set of linear piecewise affine (PWA) systems. The key advantages of this methodology are two-fold: firstly, the construction of an analytic ...
متن کاملExplicit Feedback Linearization of Magnetic Levitation System
Abstract—This study proposes the transformation of nonlinear Magnetic Levitation System into linear one, via state and feedback transformations using explicit algorithm. This algorithm allows computing explicitly the linearizing state coordinates and feedback for any nonlinear control system, which is feedback linearizable, without solving the Partial Differential Equations. The algorithm is pe...
متن کاملDigital Control of Magnetic Levitation System using Fuzzy Logic Controller
This paper deals with the control aspects of magnetic levitation system using fuzzy logic controller (FLC). The magnetic levitation system is a mechatronic system already acknowledged and accepted by the field experts. For such a system it is desired to proposed a suitable controller for positioning a metal sphere in air space by the help of an electromagnetic force. In the ideal situation, the...
متن کاملRobust Control Design of a Single Degree-of-freedom Magnetic Levitation System by Quantitative Feedback Theory
A magnetic levitation (maglev) system is inherently nonlinear and open-loop unstable because of the nature of magnetic force. Most controllers for maglev systems are designed based on a nominal linearized model. System variations and uncertainties are not accommodated. The controllers are generally designed to satisfy gain and phase margin specifications, which may not guarantee a bound on the ...
