摘要:
为了研究高速磁悬浮列车牵引控制技术,获得高性能的动静态控制性能,针对高速磁悬浮列车位置检测传输的特殊性,介绍了位置检测系统的基本构成,分析了位置信号延时产生的原因。依据交流电机磁场定向控制原理以及自动控制理论,推导了长定子直线同步电机牵引控制系统传递函数及其状态方程,分析了位置信号检测延时对牵引力控制动静态性能的影响。结果表明位置信号检测延时会造成系统稳态下牵引力损失,导致控制系统动态性能变坏,系统运行带宽减小。
Abstract:
In order to investigate the propulsion control strategy and achieve a high static and dynamic performance of high speed maglev transportation, the speciality of position measuring of MAGLEV Vehicle was taken into consideration, the construction of position measuring system was introduced and the time delay during position signal transmitted was discussed. According to the principle of vector control and automation control, the transfer function and state equations of control system are deduced. Detail analyses of the influence of the timedelay on the static and dynamic performance of the propulsion control system were given. It can be concluded that a long delay time results in the losing of thrust, destruction of decoupling ability and reduction of operation bandwidth.
