摘要
针对动车组交流异步牵引电机的空间分布性特点,讨论了基于列车通信控制网络(TCN)的牵引电机控制系统建模方法。采用输入输出反馈线性方法对牵引电机的5阶非线性模型进行线性化和解耦,之后将其引入基于TCN的动车组网络控制系统,并考虑了网络控制系统中的网络延迟。使用动态输出反馈控制方法,得到网络化的异步牵引电机控制模型。运用Lyapunov稳定性理论对闭环控制系统进行了稳定性分析,给出了系统的渐近稳定条件。
Considering the distribution characteristics of asynchronous traction motor, a modeling method was presented for networked traction control systems by introducing networked control systems (NCSs) into the asynchronous traction motor driving system. The NCSs of EMUs was based on the train communication network (TCN). It was assumed that the network time delay occurred in the transport medium of network data. A feedback linearization method was used to achieve the input-output linearization and the decoupling of the asynchronous traction motor driving system based on a fifth-order model of an asynchronous traction motor. Using the dynamic output feedback control method, a networked control model of an asynchronous traction motor was established. By using Lyapunov functional approach, the sufficient condition of asymptotic stability was given.
