In this study, a speed-sensorless direct torque control (DTC) system using bi input-extended Kalman filter (BI-EKF) is designed to perform the high performance velocity control of induction motors (IMs). The BI-EKF algorithm estimates stator stationary axis components of the stator fluxes, tpsa and tpsfl, the rotor angular velocity, omega(m) the rotor resistance, R-r', the stator resistance, R-s, the load torque involving the viscous friction term, t(L), and the reciprocal total inertia of the IM and load, gamma(T) =Delta 1/j(T), as well as stator stationary axis components of stator currents, i(s alpha) and i(s beta), which are also measured as output. The simulation results prove very satisfying performances of the BI-EKF algorithm and therefore the speed-sensorless DTC system.

Speed Control by Sliding Mode of Synchronous Motor
Bahi, T.; Lachtar, S.; Soufi, Y.; Lckhchine, S.; Merabet, H. (2011-09-10)
This paper presents the results of a simulation for synchronous motor speed control using a Direct Torque Control (DTC). This technique was object of a deep study for synchronous motor drives instead of precise closed loop speed control. However, this technique presents some problems such as, high influence of the motor parameters. The sliding mode controller is a model-based approach used to improve the robustness of the control law despite this influence and to illustrate the good performance of this tech...
Wide-Speed Range Control Strategy for a 8/6 Switched Reluctance Machine
Pop, A. C.; Petrus, V.; Martis, C. S.; Iancu, V.; Gyselinck, J. (2011-09-10)
A control scheme for obtaining low torque ripple and high efficiency for a minimal reduction in average torque as compared to its maximal value is presented for a four-phase switched reluctance motor. At low speed, the torque ripple is minimized by the means of current profiling techniques. As the speed increases the controller switches to optimal firing angle control strategy. The optimal values for the angles are obtained based on minimization routine for different objective functions. Starting from the o...
Optimum Profile Modifications for the Minimization of Dynamic Transmission Error
ÖZTÜRK, VEYSEL YALIN; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2014-08-28)
An optimization study is performed target being the reduction of dynamic transmission error (DTE) for a selected operational range, where the operating torque and speed ranges are defined. For this purpose, two different models, i.e. a single degree of freedom (SDOF) lumped gear dynamics model and a multi-degree of freedom (MDOF) lumped model of a gear pair which is combined with shaft and bearing dynamics are employed. The differences between the optimization results obtained through loaded static transmis...
Optimum geometry for torque ripple minimization of switched reluctance motors
Sahin, F; Ertan, HB; Leblebicioğlu, Mehmet Kemal (Emerald, 1995-12-01)
This paper briefly describes an approach to determine the optimum magnetic circuit parameters to minimize low speed torque ripple for switched reluctance (SR) motors. For prediction of the torque ripple, normalized data obtained from field solution and a neural network approach is used. Comparison of experimental results with computations illustrates the accuracy of the method. The optimization method is briefly described and some results are presented.
An analytical approach for determination of optimal stator/rotor saliency number of a swıtched reluctance motor
Kılınç, Cem Erkan; Bostancı, Emine; Department of Electrical and Electronics Engineering (2020)
The purpose of this study is to seek the optimal stator and rotor saliency number of a switched reluctance motor (SRM) for hybrid electrical vehicle (HEV) applications. For this purpose, first a previously developed SRM analysis software is investigated to identify possible errors in implementation of both the theory and the coding. Performance prediction method is based on the use of normalized force and permeance data produced via numerical field solution, and a polynomial based interpolation is introduce...
