long with the dramatic development of electronic technology and computer science, the speed regulation technology of alternating current motor has made considerable progress. Analysis of a kind of full-order closed-loop flux estimator which provides the accurate rotor flux is given. Speed auto-rate is deduced based on Lyapunov Theory. On this basis, the simulation platform is built in Matlab/Simulink environment. The results show the full-order flux observer has high estimation accuracy on rotor flux; the given system has good steady state performance and dynamic performance in its full range.
