摘　　要：此处在双馈电机定子磁链定向数学模型下,提出采用矩阵式变换器(MC)作为主电路,调节矿用提升机转子侧绕组输入电压的控制系统。提升机带负载加减速运行时可实现能量的双向流动,节能效果明显。通过MC调节转子绕组电流实现平滑调速,改善提升机动态性能,定子侧输入功率因数可调,能减少对电网的干扰。MC采取简化的间接空间矢量调制策略,运用Matlab,对新控制系统进行仿真研究,然后进行模拟实验,结果验证了所提方法的可行性。The matrix converter（MC） is proposed as the main circuit for mine hoist control system of the rotor wind- ing input voltage under the double-fed motor stator flux-oriented mathematical model.It can realize two-way flow of power and save energy effectively when the hoist operate with deceleration on load.Besides,it can adjust the power factor of stator side through controlling rotor current by MC to improve dynamic performance of the motor, reduce the disturbance to the grid.The control system simulation model is built based on space vector modulation of MC in Mat- lab environment, and then completed the simulated experiments, the results verify the feasibility of the scheme.
