| Abstract: | This paper introduces the basic principle of direct torque control system for asynchronous motor, gives a method of speed estimate based on adaptive full-step flux observer and realized the speed identification under the condition of speed sensorless. the simulation model of this system based on Matlab/Simulink is developed, Simulation result show that this method gives satisfied estimation of stator flux and rotor speed,especially in lower speed range. |
