Summary:This paper presents a novel technique of an sensor less indirect stator field-oriented IM (induction motor) drive speed control, which prevents the accumulative errors caused by the stator resistance is susceptible to temperature variations while conducting the flux estimation directly and computing the synchronous rotary speed. First, the research adds an adaptive flux observer to estimate the speed of the rotor. Secondly, using the fixed trace algorithm (FTA) to estimate the rotor resistance, thereby improving the problem of stability at the low speed in regenerating mode and the influence. Finally, the paper conducts simulations and practices of Simulink® of MATLAB® to verify the correctness of the result of the paper.
