摘要
针对动车组交流异步牵引电机的非线性、强耦合特征和空间分布性特点,讨论了基于列车通信控制网络(TCN)的牵引电机逆解耦控制。对牵引电机非线性模型应用逆系统方法,将其解耦成转子磁链和转子转速两个线性子系统,将线性化后的牵引电机模型引入基于TCN的动车组网络控制系统,考虑了网络控制系统中的不确定网络时延对系统的影响。使用动态输出反馈控制方法,建立了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,给出了系统的稳定条件。以基于TCN标准的CRH3型高速动车组的交流异步牵引电机为研究对象,根据线性矩阵不等式方法求解网络控制器参数,利用Truetime仿真工具箱验证了牵引电机网络化逆解耦控制方法的有效性和可行性。
Considering the nonlinear,strong coupling and distribution characteristics of asynchronous traction motor,a method based on inverse decoupling control was used to study networked traction motors control systems.Using inverse system method with nonlinear mathematical model of traction motors,the control systems were decoupled into two independent linear subsystem. Linear model of traction motors were introduced into the networked control systems of EMUs which are based on the train communication network. It was assumed that the uncertainty network time delay occured in the transport medium of network data. Using the dynamic output feedback control method,a networked control model of asynchronous traction motor was established. The sufficient condition of robust stability was given by using Lyapunov functional approach. Using linear matrix inequalities method to solve the network controller parameters,and Truetime the simulation toolbox was used to verify that the method of networked inverse decoupling control is effective and feasible for traction motor of CRH3 EMU.
