转差频率矢量控制系统PI调节器参数计算

转子磁场定向的矢量控制动态性能好,转矩响应速度快,磁链模型简单,可增强列车的防滑和抗负载扰动能力,已被广泛应用于高速列车交流牵引领域。矢量控制是基于动态电机模型的控制,所以其对控制环节中PI参数的选取和精度十分敏感,本文将工程设计方法应用到转差频率矢量控制系统PI调节器设计中,将电流环分解为两个独立系统;实现了动态下转矩和磁通的完全解耦,使得PI调节器参数整定问题大为简化。仿真结果表明,该系统具有良好的稳、动态性能,可以对电流和转速进行高性能的控制。

Parameters Count of PI Regulators for Slip Frequency Vector Control System

As the advantages of good dynamic performance,fast torque response,simplified magnetic chain model,the ability to enhance the train to prevent slipping and resist load disturbance,the rotor field-oriented vector control method which is based on dynamic mathematical model of ac motor,has been widely applied in high-speed train ac traction. Nowadays,vector control has been successfully used in metro and city tram's main transmission system at home and abroad.There are mainly two kinds of vector control strate...
