摘要
针对采用传统直流调速系统的矿用电机车在实际运行过程中存在维护量大、故障率高等问题,设计了一种基于永磁同步电动机的矿用电机车交流调速系统。该系统以TMS320F28335为控制核心,配合电流采样、转速测量等外围电路,采用直接转矩控制策略,实现了对电机车的高精度控制。实验结果表明,该系统调速性能良好、动态响应速度快、维护量低。
In view of problems of large amount of maintenance and high failure rate existed in actual running process of mine-used electric locomotive used traditional DC speed regulation system, a speed regulation system of mine-used electric locomotive based on permanent magnet synchronous motor was designed. The system uses TMS320F28335 as control core and realizes high-precision control of the electric locomotive combining with strategy of direct torque control as well as peripheral circuits of current sampling, speed measurement. The experimental result shows that the system has good speed regulation performance, fast dynamic response and less maintenance.
