Simulation Results

It has been proposed that the traction and levitation of the carrier in the maglev system are controlled by the thrust and attractive force generated in Linear Induction Motor (LIM). In this system, the thrust and attractive force of LIM are controlled simultaneously and independently by the two different frequency components. In this paper, it is proposed to use the frequency component synchronous with the motor speed as one of the frequency components. It makes the design of the controller easier. The controller is designed using the measured parameters of LIM. It is verified that both the traction and levitation control are achieved by the simulation results.

In this paper a model fuzzy predictive force control (FPFC) for the speed sensorless control of a single-side linear induction motor (SLIM) is proposed. The main purpose of of predictive control is minimizing the difference between the future output and reference values. This control method has a lower force ripple and a higher convergence speed in comparison to conventional predictive force control (CPFC). In this paper, CPFC and FPFC are applied to a linear induction motor and their results are compared. The results show that this control method has better performance in comparison to the conventional predictive control method.
