摘　　要：本文提出了一种新型的串联双模型转速、磁链观测器，该观测器解决了常规并联双模型观测器存在的缺点，可实现电机转速、磁链的同时观测。在此基础上，构造了一异步电机无速度传感器矢量控制系统。仿真研究和实验结果证明了该系统有较高的动、静态性能。A novel series dual model speed and flux observer is proposed in this paper. The observer can solve theproblem of initial integration error caused by usual parallel dual model observer and can observe rotor speed and fluxlinkage simultaneously. On the basis of the observer,a speed sensorless vector-controlled induction motor drive systemis designed. Simulation and experiment results validate that the system bas satisfactory static and dynamic performance.
