基于力矩模式的矿山牵引电机车控制系统的研究与实现

Study and Implement on Control System of Traction Locomotive Based on Torque Model

为克服矿山牵引电机车运行方式切换机车运行平稳性差等缺点,研究转子磁链定向矢量控制系统,采用力矩模式控制策略,有效克服了采用传统控制方式下减速、制动过程中引起的电压泵升对直流母线带来的威胁。控制系统输出力矩直接可控,操作方便、结构简单。试验验证系统运行平稳、可靠,满足矿山牵引电机车控制的需要。

In order to overcome the poor stationarity of traction locomotive during the operation mode switching.Rotor flux oriented vector control theory based on,torque model control strategy adopted,it could overcome the DC bus pumping as Locomotive deceleration and barking,in this system,output torque could be controlled directly,experiments verification the system had good performance of stability and reliability,its could meet the traction locomotive control needs.
