摘要
磁链观测一直是异步电机无速度矢量控制的难点,本文以异步电动机本身为参考模型,设计了全阶观测器的可调模型来估算异步电机的磁链和速度。利用Matlab软件构造了按转子磁场定向的矢量控制系统的仿真模型,采用全阶观测器的方法在逆变器仿真平台和实验平台上实现了异步机的无速度矢量控制。通过仿真和试验验证了模型的正确性,结果表明所建立的调速系统具有良好的动态性能。
It is difficult to observe flux in the induction motor sensorless vector control. In this paper, the induction motor is the reference model, the design of the adjustable model of the full order observer to estimate the flux and speed of the induction motor. Cconstructssimulation model of rotor magnetic field oriented vector control system based on the MATLAB software, sensorless vector control of an induction motor fed by inverter simulation and experimental platform is realized based on a full order flux observer.Results show that it has good dynamic performance, andit realizes.
