【 摘 要 】

The filthy and wet environment of coal mines has always been unfavorable to the proper functioning of electric locomotive. It usually suffers from limited speed feedback signal because the speed sensor is flooded with water and stopped, resulting in its malfunctioning. It often deviates from its track, crashes, or incurs other accidents. To solve these problems, this study employs an embedded processor (i.e., ARM) as the control core to design a speed -sensorless. Vector control system for electric locomotive. A vector estimation method of magnetic linkage and rotational speed of rotor is also provided. In addition, the rationality of the system hardware design and the correctness of the estimation method are verified.
