An incremental motion control problem, specified by a trapezoidal speed command profile using multisegment sliding mode control (MSSMC), is proposed to control synchronous reluctance motor (SRM) servo drive. Since the control gains in the MSSMC are fixed, chattering responses occur due to large external load disturbances. Therefore, a neural network (ANN) is developed to tune the control gains ...

Abstract. The Switched Reluctance Motor (SRM) Drives have attracted the attention of many researchers in the recent past because of advantages like simple mechanical structure, adaptability to harsh environments like coal mining etc. But it has one main disadvantage of high torque ripple due to its double saliency structure. The Direct Torque Control (DTC) technique can minimize the torque ripp...

Abstract: The primary objective for this paper is to create a methodology to rapidly optimize double-stators switched reluctance motor (DSSRM). An analytical model of equivalent magnetic circuits for the air gap reluctances of aligned and unaligned positions is proposed and the optimal operation point of the magneto-motive force (MMF) can be determined.

The concept of this work helps to develop a switched reluctance motor (SRM) drive. Because of salient feature like four quadrant, rigid structure, high-speed capability and low cost from other types of motors, switched reluctance motor is more predictable in high speed applications. Its on-board integrated charger is formed using the embedded motor drive components. Good driving and regenerativ...

This paper presents passive boost converter fed three phase switched reluctance motor using PI Controller. The operating mode of proposed converter circuit is discussed. The proposed converter is capable of minimizing the torque ripple because of faster excitation and demagnetization and also improving the average torque compared to the conventional converter circuit.

Vibration is one of the major drawbacks of Linear Switched Reluctance Motor (LSRM). Two design techniques to reduce vibration in the LSRM are proposed. A detailed mathematical approach for calculating natural frequency has been outlined. Different techniques to predict the vibration frequencies are analyzed using ANSYS software. The analyzed structures are compared by using experimental and sim...

Because of extreme local saturation at pole tips of excited phase and uncircular shape of rotor and stator, a Swithed Reluctance Motor (SRM) does not have a simple and accurate mathematical model. Therefore, the output control of this motor requires a robust controller which is not based on an accurate model of the process. Fuzzy controllers, to some extent, will satisfy these requirements. Tet...

The energy utilization ratio (ER) quantifies the of a Switched Reluctance Motor (SRM). Calculation ER an SRM can be different from other motors as it has highly non-linear operating characteristics and uses asymmetric bridge converter.
