Abstract :
This paper deals with the design and enactment of a hybrid controller for the magnetic levitation system. This hybrid controller comprises of two types of controllers. One is based on mathematical model and other does not depend on it, so mathematical inaccuracy in the modeling of the system can be handled by other controller. Takagi-Sugeno Fuzzy logic controller (FLC) and Linear Quadratic Regulator (LQR) are used together in a hybrid manner. LQR is designed for improving the performance using full state feedback control and T-S fuzzy controller is designed for accommodating nonlinearity using IF-THEN rules. Based on the analysis of simulation results and real time response of magnetic levitation system, the hybridization of the FLC with LQR shows a superior result than FLC alone.
