Takagi-Sugeno fuzzy controller for a magnetic levitation system laboratory equipment

This paper presents the design and the implementation of two control solutions applied to a magnetic levitation system laboratory equipment. The first solution deals with a state feedback control structure to stabilize the controlled plant which is the inner control loop for the cascade control system structure proposed as the second solution. The second solution is based on a Takagi-Sugeno fuzzy controller in the outer control loop to ensure the zero steady-state control errors. Simulation and real time experimental results are included to illustrate the performance of the control systems and to validate the two control solutions in regulation and tracking.
