摘要
本文基于空间矢量调制技术应用于永磁同步电机直转矩控制系统用以改善混合动力汽车永磁同步电机直接转矩控制中混合动力汽车低速的运行性能,可以降低了传统的直接转矩控制系统的转矩脉动和磁链脉动,使控制系统有较高的响应速度和较强的鲁棒性,同时有效地扩大了系统调速范围。并用Matlab/Simulink软件建立了该直接转矩系统的仿真模型,仿真结果表明了该方法在永磁同步电机直接转矩控制系统中的有效性。同时在混合动力汽仿真软件Advisor中,显示了控制策略对汽车起动和低速运行中快速性与稳定性的提升。
In the paper, voltage space vector modulation technology is used for direct torque control of hybrid electric vehicles (HEV) permanent magnet synchronous motor (PMSM), which can weaken the ripple of torque for improving HEV low speed course performance, therefore the control system get swifter response velocity, stronger robustness and higher precision of velocity control. The computer simulated software results verify the validity of this novel method. Simultaneity HEV simulated software Advisor show the strategy is valid in improwing HEV system s tart up quickily and statblily.
