提出一种用于矿用电驱动铰接车基于功率分配的整车控制策略。发动机-发电机组采用基于油门踏板功率信号和恒磁通励磁PI调节的控制策略,电动机驱动系统基于功率-电流双闭环控制,车辆转向通过等转矩跟随控制自适应差速。建立了包含ADAMS铰接车动力学和MATLAB/Simulink电动机驱动系统的联合仿真模型,对车辆在平地、上坡及不同载重工况下的直行和转向进行仿真,仿真结果表明该控制方案使车辆具备良好的加速性能和转向性能。结合试验验证了转向控制策略的可行性及联合仿真的正确性,为电驱动铰接车的研制提供了技术基础。
A vehicle control strategy based on power distribution for mining electric drive articulated vehicle is proposed. The engine-generator set adopts the control strategy based on the accelerator pedal power signal and constant flux PI control. The motor drive system is based on the power-current double closed-loop control and the vehicle steering is controlled by the torque follow-up control adaptive differential. A joint simulation model including ADAMS articulation dynamics and MATLAB / Simulink motor drive system was established to simulate the straight-ahead and steering of vehicles under the conditions of flat ground, uphill and different load conditions. The simulation results show that the control scheme makes the vehicle well Acceleration and steering performance. The feasibility of the steering control strategy and the correctness of the co-simulation are verified by the combined test, which provides a technical basis for the development of the electrically driven articulated vehicle.
