磁链观测是矢量控制中的一个关键任务,电流模型在转速较低时比较精确,电压模型在转速较高时比较精确。结合两种模型使其依靠程序自动切换,在转速较低时使用电流模型,在转速较高时采用电压模型,可以对磁链进行准确的观测。以 Matlab/Simulink 为工具,采用程控自动切换混合模型对异步电机矢量控制算法进行了仿真。仿真结果验证了程控自动切换的可行性和矢量控制调速的动态响应快、硬特性强、稳态脉动小的良好性能。

Flux observation is a key tast in vector control.The current model is more precise speed,while the voltage model on the contrary.A combination of the two models can have an accurate observation of the flux,with current model at low speed and voltage model at high speed based on the automatic changing of the software.A hybrid model of the current and voltage will be presented at this paper based on the tool of Matlab/Simulink.The simulation results verify the feasibility of the program controlled hybrid model and present a fast resposing,hard characteristics and low state ripple about the vector control strategy.
