| 针对高速列车二极管中点箝位三电平拓扑牵引逆变器-牵引电机系统运行控制的要求，对牵引电机运行全速度范围中基于转子磁通控制的变频调速控制方式进行了分析，给出了转子磁场定向间接矢量控制功能框图并对实现算法进行了详细阐述。考虑死区效应和PWM采样误差的影响提出了三电平牵引传动主电路精确建模的补偿算法，建立了基于dSPACE半实物仿真平台的牵引传动主电路实时仿真模型，根据上述理论分析编制了基于TMS320F2812型DSP的牵引传动控制实现算法。对该控制算法在不同的主电路模型实现算法和不同计算步长下的实时仿真实验结果进行了对比分析，结果验证了该牵引传动主电路实时仿真建模算法和传动控制算法的有效性。 |

| Abstract: |
| The variable-frequency speed regulation based on rotor flux control for the traction inverter-motor system with three-level diode NPC（Neutral-Point-Clamped） topology is analyzed covering whole speed range of high-speed train. The functional block of rotor-flux-oriented indirect vector control is given and its implementation algorithm is discussed in detail. The compensation algorithm for the precise modeling of the main circuit of three-level traction drive is presented，which considers the effect of dead-time and PWM sampling error. Its simulation model is built based on the hardware-in-the-loop real-time simulation platform of dSPACE and the traction drive control algorithm is programmed based on TMS320F2812 DSP. The comparison of control performance among different main circuit realization methods and among different calculation steps demonstrates the validity of the real-time simulation modeling algorithm and the drive control algorithm. |
