摘要:
在牵引电传动系统中,由于高电压、大电流的特点,同时受到开关损耗和散热等条件限制,逆变器的最高开关频率通常较低,只有几百赫兹。在这种情况下,永磁同步电机控制系统中的电流控制性能较差。为此,在复矢量法分析的基础上建立了包含延时影响的离散数学模型(脉冲传递函数),并采用最少拍系统设计方法确定电流调节器,针对数学模型在低速启动时不准确的问题,提出了补偿方案。通过仿真和现场试验结果证明,采用所提电流调节器在低速大电流启动和高速运行时,反馈电流都能很好跟随给定电流,电磁转矩也能完全跟随给定转矩;并且在加、减挡位时,电流和电压具有较好的稳态性能和动态性能。
Abstract:
In the traction electric drive system, due to the characteristics of high voltage and high current, as well as the conditions of switching loss and heat dissipation, the maximum switching frequency of the inverter is usually low, which is only a few hundred Hz. In this case, the current control performance of the permanent magnet synchronous motor control system is poor. For this reason, a discrete mathematical model (impulse transfer function) including the influence of delay was established based on complex vector analysis, and the current regulator was determined by the least-shot system design method. Finally, according to the problem of mathematical model was not accurate at low speed, the compensation plan was put forward. The simulation and field test results showed that the feedback current could follow the given current well and the electromagnetic torque could exactly follow the given torque when using the current controller at big current start and high speed operation conditions. Moreover, the current and voltage have better steady-state and dynamic performance when the gears are added or shifted.
