Abstract

This paper aims at the development of a proportional integral derivative (PID) controller with a derivative filter coefficient for a magnetic levitation system (MLS), which is a highly nonlinear open loop system. The mathematical modeling of MLS is done using MATLAB/Simulink. The proposed controller simulation results are evaluated with sine wave and step response. The results obtained are also compared with PID controller. The response of the proposed PID controller with derivative filter show better response in comparison to that of conventional PID controller.
