| Popis: | Magnetic levitation maglev has been a keen area of research, especially in the field of transportation. Maglev is used in order to reduce the maintenance cost, increase the efficiency and thereby the useful life of the system is increased. Controlling the maglev system is not an easy task. Literature shows several authors have proposed different controllers to stabilise the position of the object in the air. The main drawback is that the controllers are designed by neglecting the eddy-current-based force due to the motion of the levitated object. This paper presents an analytical relation for the eddy current-based force as a function of the plate thickness and its distance to the permagnet. A model reference adaptive PID controller is proposed to reduce vibration in the object. The efficacy of the proposed controller is tested on a maglev system considering the eddy current-based force. |
