This paper aims at the problem of the poor performances of motor with low speed caused by the flux observation errors in the direct torque control of asynchronous machine with speed sensor-less,and the closed loop flux state observer is adopted to observe and measure the flux,on the basis of which,the simulation study is made of the adaptive rotor speed identification method and the direct calculating rotor speed method respectively.And also,the advantages and disadvantages of two methods are… CONTINUE READING
