Abstract :
In this paper a new method is proposed for determining PID controller
parameters in order to decrease losses in levitation system of magnetic
trains. It is assumed that this system is a hybrid system and it consists of
electric and permanent magnet. For optimization of losses initially AC
losses of magnetic levitation system are calculated. Linear model of
levitation system as well as modeling the system is offered. The parameters
related to PID controller are tuned with Ziegler–Nichols method and
optimizing methods using genetic algorithm. The corresponding results are
compared.
