| 摘 要： | 为了研究CRH3型动车组恒速控制器所适合的控制策略,分别分析了PI调节器和双滞环调节器两种恒速控制策略的原理,并将这两种恒速控制器应用于牵引电机矢量控制系统中,通过MATLAB/Simulink对其进行仿真研究。仿真结果表明,采用双滞环调节恒速控制器可使动车组在牵引、恒速、制动工况间平滑切换,转矩、磁链波动较小,是适合CRH3动车组采用的一种恒速控制策略。

| Abstract: | Aiming at studying the constant-speed control strategy appropriate for CRH3 EMU,the constant-speed control principle of PI regulator and double-hysteretic band regulator are both analyzed respectively,and the two constant-speed controllers are applied to vector control system of traction motor,also simulation study is made by MATLAB/Simulink.Simulation results show that smooth switching among traction,constant speed and braking mode can be realized when adopting double hysteretic band constant-speed controller,and fluctuation of torque and flux is small,which is a constant-speed control strategy suitable for CRH3 EMU. |
