Abstract

This paper presents an analog fuzzy logic based controller applied to a magnetic levitation system. This system is nonlinear and complex, so it is difficult to obtain exact mathematical model. To improve control performance, an analog fuzzy supervisory lead phase controller has been used. The proposed controllers for magnetic levitation system is simulated by using MATLAB-SIMULINK and implemented on an experimental system using a PIC 18F4550 microcontroller.
