DSP implementation of fuzzy controlled magnetic levitation system

Abstract

This paper presents a fuzzy logic based controller applied to a magnetic levitation (MAGLEV) system. MAGLEV system is nonlinear and complex. It is difficult to obtain exact mathematical model. To improve control performance, an inner current control loop has been used. The proposed controllers for MAGLEV system is simulated by using MATLAB-SIMULINK and implemented on an experimental system using a TMS320C31 digital signal processor.
