Control of magnetic levitation system using adaptive PID controller

Currently, magnetic levitation (maglev) technology has begin to be developed and applied in several field, such as in the fields of transportation, promotional and learning media. The control of Maglev to levitate smoothly and accurately is still challenging problem that need to be solved. In the control field, there two type of reference position of maglev that to be reached by the maglev system, such as waypoint tracking or trajectory tracking. In this paper, the proposed controller is used to control the maglev to track waypoint and trajectory. The control system of magnetic levitation is important to levitate the metal object. The Adaptive PID control based on frѐchet Tuning Algorithm system is applied to control the solenoid maglev. Based on simulation result, the proposed controller is able to tune the PID controller to control the magnetic levitation adaptively. However, the steady state error still occured in trajectory tracking.
