摘要
文章以地铁永磁直驱系统为对象,具体阐述了牵引传动与动力学机电耦合半实物仿真系统的设计与实现过程,首先建立地铁永磁直驱牵引传动系统主电路的“CPU+现场可编程门阵列(FPGA)”模型,将其与车载牵引控制器(TCU)实物进行联合调试仿真,并通过对比仿真结果与地面联调试验数据进行验模,仿真结果与设计目标转矩的相对误差满足±5%的要求;然后联合车辆动力学模型,搭建牵引传动与动力学机电耦合半实物仿真平台,通过牵引传动模型对车辆动力学模型施加电机转矩,并将车辆运行速度反馈给牵引传动模型,实现牵引传动和动力学的动态协同仿真。结果表明,车辆动力学响应可反映电机转矩脉动的影响,计算结果的频率成分更加丰富,更加符合真实情况,与单学科仿真相比更加具有优势。
This paper takes the metro permanent magnet direct-drive system as the object,and expounds the design and implementation process of the semi-physical simulation system for electromechanical coupling of traction drive and dynamics.Firstly,the“CPU+field programmable gate array(FPGA)”model of the main circuit of the metro permanent magnet direct-drive traction drive system is established,and it is jointly debugged and simulated with the vehicle traction control unit(TCU).By comparing the simulation results with the ground jointtuning test data,the modle is verified.It can be seen that the relative error between the simulation results and the designed target torque meets the requirement of±5%.Combined with the vehicle dynamics model,a semi-physical simulation platform for electromechanical coupling of traction drive and dynamics is built.The motor torque is applied to the vehicle dynamics model through the traction drive model,and the vehicle running speed is fed back to the traction drive model to realize the dynamic co-simulation of traction drive and dynamics.The results RTshow that the vehicle dynamic response can reflect the influence of the pulsation of the motor torque,and the frequency component of the calculation result is more abundant and more in line with the real situation,which is more advantageous compared with single-discipline simulation.
