摘　　要：提出基于磁通观测的电流前馈型解耦矢量控制系统结构,给出了异步电动机的数学模型,根据实际系统建立了基于Matlab/Simulink平台的实验仿真系统,该系统具有很强的移植性和扩展性.利用该系统对基于磁通观测的电流前馈型解耦矢量控制系统进行了分析研究,加快了动态转矩的变化,明显提高了系统的动态性能.可用来验证矢量控制系统在各种参数下系统的控制特性,可用于各类基于转子磁场定向的电流型解耦矢量控制应用系统,从而大大缩短新产品的开发周期.经实践具有一定的实用价值.A forward-feed current decoupling vector control system, based on flux observation, was brought forward. The mathematical model of the induction motor system was presented. The simulation system, developed under Matlab/Simlink platform according to the real system, worked efficiently. The dynamical performance of forward feed current decoupling vector control system based on flus observation, was studied with this simulation system. The change of the system dynamical torque was accelerated to improve, the system dynamical performance. The system can be used to verify the controlling characteristics of vector control system with different parameters. It can be also used for different forward-feed current decoupling vector control systems based on flux observation. It reduces the development time of new products and has practical value.
