摘　　要：矿用电机车为煤矿井下的辅助运输工具,由于井下恶劣的工作环境,影响到电机车的可靠性和工作效率。为了提高矿用电机车控制系统的技术性能,提出采用永磁同步电动机驱动及模糊滑模控制方案,设计了模糊滑模速度控制器,采取指数趋近律来降低滑模控制的抖振现象。对所提的矿用电机车永磁同步电动机的控制策略,在加减速和爬坡等实际工况进行了系统仿真,并与传统PI控制器进行了比较分析,结果表明模糊滑模控制有着更好的控制性能,有助于平稳调速,增强抗干扰能力。Mining locomotive is an auxiliary transportation tool in the coal mine,and the reliability and work efficiency of the electric locomotive will be affected due to the harsh working environment underground.In order to improve the technical performance of the control system of the mining locomotive,a permanent magnet synchronous motor drive and sliding mode control scheme were proposed,and a fuzzy sliding mode speed controller was designed,and the exponential approximation law was adopted to reduce the jitter phenomenon of the sliding mode control.The proposed permanent magnet synchronous motor control scheme for mining locomotive is simulated under the actual working conditions of acceleration,deceleration and climbing,and compared with the traditional PI controller,and the results show that the fuzzy sliding mode controller has better control performance,which can make the mining locomotive have stable speed regulation and strong anti-interference ability.
