Authors: A.S. Haider and U. Nasir and M. Mujtaba and M.D. Ahmed
Abstract: This research paper presents controller design for Magnetic Levitation System using modern discrete time control theory approach. Zero-Order-Hold (ZOH) method is used to discretize the Jacobian linearization state space magnetic levitation dynamic model. This model is used to design minimum order state estimator using Diophantine’s Polynomial approach which implicitly implements state estimation. Pole assignment is used for state feedback. Response of the controller and estimator is kept Dead-Beat. Difference equation of the designed controller is implemented on digital controller interfaced with digital computer for real time monitoring. Simulation and hardware testing results show that this approach is intuitive, simpler, gives good transient control performance and superior overall response of the system to the noise
Keywords: Diophantine state estimator, minimum order polynomial observer, Dead beat, Pole assignment,
