Design of Continuous Time Controller for Adjusting Magnetic Levitation System Performance Variables
Summary:
In this thesis, in chapter 1, reference is made to various applications that use the method of magnetic levitation. Reference is made to the most important ones and the importance of this method nowadays is emphasized. Also in chapter 2 the problem of controlling the position of a magnetically levitating sphere by means of a linear PD state feedback controller and simultaneously satisfying a set of individual different design requirements is studied, including stability, following the command, following the model and the appropriately bounded input. The requirements are determined on the linear approximation of the magnetic levitation system. Also, to solve the problem, a meta-heuristic algorithm is proposed, based on the linear approximation of the magnetic levitation system. The performance of the proposed control system for the resulting nonlinear closed-loop system is illustrated through a series of computational experiments.
