摘　　要：为了提高矿用机车无刷直流电机控制精度和稳定性,利用MATLAB中的Simulink的仿真环境,搭建出理想的仿真模型。在分析滑模控制系统理论基础上,加入自抗性改进滑模变结构的控制方案。仿真结果表明,此方案更有利于瞬态响应的实现和提高控制稳定精度,能够对负载突变迅速地做出响应,具有较强的抗干扰性,提高了系统的整体性能。实验结果表明此控制策略可行。In order to improve the control accuracy and stability of brushless DC motor for mine locomotive, an ideal simulation model is built by using the Simulink simulation environment in MATLAB. Based on the analysis of the theory of sliding mode control system, the control scheme of self-resistance improved sliding mode variable structure is added. The simulation results show that this scheme is more advantageousto the realization of transient response and the improvement of control stability precision, can respond quickly to load mutation, has strong anti-interference, and improves the overall performance of the system. The experimental results show that this control strategy is feasible.
