摘要
This paper presents a reciprocal power-fed linear induction motor (LIM) drive test rig for linear metro. Two inverter-fed linear induction motors on a common shaft are used in this test rig. One is as the drive motor, and the other is as the traction load. The DC links of both inverters are connected to each other to circulate the energy, and supplied from the AC mains through a four-quadrant converter. In this paper, the dynamic model of LIM is derived firstly. Then the dynamic emulation of mechanical loads is discussed, and two control strategies for both motors are presented. Lastly, simulation results are given to verify the validity of the proposed linear induction motor drive test rig.
