This paper be described the constant speed control of induction motor for high performance. Vector control system which is used the stator current, voltage of IM is modeled without the speed, flux sensor. The proposed control system be simulated using Matlab with Simulink. Results include the fast response of the constant speed and torque in proposed system. For high performance, this paper presents the robust characteristics of field oriented control system for IM.<br/> <br/>

This paper introduces a new rotor position estimation algorithm for the SRM, based on the magnetizing curves of aligned and unaligned rotor positions The flux linkage is calculated by the measured data from phase voltage and phase current, and the calculated data are used as the input of magnetizing profiles for rotor position detection. Each of the magnetizing profiles consisted of the methods using the neural network and fuzzy algorithm.<br/> And also, the optimal phase is selected by phase selector. To demonstrate the promise of this approach, the proposed rotor position estimation algorithms are verified by the experiment results for variable speed range
