Abstract :
Magnetic Levitation is a complex nonlinear mechatronic system and consequently poses a challenging control problem. We propose real time adaptive and nonadaptive controllers based on fuzzy state feedback to stabilize the system using the Lyapunov criterion. We employ Takagi-Sugeno formulation to model our system. The proposed controller is divided into 2 parts - the first part stabilizes the nominal plant without taking into account the modeling uncertainties and the second part accounts for the same. Further, we simulate such a system using MATLAB and establish the effectiveness of our control paradigm and finally discuss the merits and demerits of the same.
