Abstract
This work describes the control design and implementation for a magnetic levitation system. The system is composed by a Y shape iron plate that must be levitated by the control of electromagnetic forces. The system is nonlinear, open loop unstable and multivariable, whose inputs are represented by voltages applied to three electromagnets and the outputs are represented by three plate positions. A controller must be designed so that the plate positions track input references with adequate performance. The proposed method to control the system uses Glover-McFarlane H∞ loop shaping design. This method is a combination of H∞ robust stabilization with classical loop shaping and presents good performance and robustness when applied to several control problems. For the evaluation of controller, numerical simulations results were obtained with Matlab/Simulink. The numerical simulation results indicate that the controller presents stability, good performance and robustness.
