同轴联接双电机驱动系统建模及仿真

Modeling and Simulation of Coaxial Connected Dual Motor Drive System

在交流传动系统试验中,由于客观条件的限制,一些电机的动态特性难以直接观测甚至无法获得,如电机的电磁转矩、实际磁链大小与位置,这给试验分析过程带来了困难。基于自适应全阶磁链观测器和转矩传感器模型,建立了能量互馈型同轴联接双感应电机交流驱动系统对应的双电机矢量控制系统的仿真模型,能够实现对系统的各种动态响应进行直接观测与测试,为实际系统控制方案的分析与研究提供了良好的参考。

Due to the objective constraints, dynamic characteristics of the motor is observed difficultly, even can not be obtained in AC drive system test, such as electromagnetic torque and the amplitude and location of actual flux. It led to the difficulties for experiment analysis. Referring to reciprocal power-fed coaxial connected AC drive, dual induction motor vector control system simulation model based on the adaptive full-order flux observer and torque sensor model was established to observe or test variety of system dynamic response directly.
