This paper presents a sliding mode observer for sensorless operation of SRM (switched reluctance motor) drive. Design of such an observer depends mainly on the nonlinear model of SRM. In this technique, neither extra hardware nor huge memory space arenot required but it only requires active phase measurements. Furthermore, PI (proportional integral) are suggested to operate individually along w...

In this paper a fuzzy expert system for predicting the performance of a switched reluctance motor has been developed. The design vector consists of design parameters, and output performance variables are efficiency and torque ripple. An accurate analysis program based on Improved Magnetic Equivalent Circuit (IMEC) method has been used to generate the input-output data. These input-output data i...

This paper describes methodology to calculate required motor power rating for elevator and lift application. Switched reluctance motor an excellent candidate for traction applications contributes more in low speed-high torque application. Quality of lift is analyzed by its smoothness, without any jurg. Torque production in motor during acceleration and deceleration decides Smoothness of lift. I...

An adaptive online flux-linkage estimation method for the sensorless control of switched reluctance motor (SRM) drive is presented in this paper. Sensorless operation is achieved through a binary observer based algorithm. In order to avoid using the look up tables of motor characteristics, which makes the system, depends on motor parameters, an adaptive identification algorithm is used to estim...

The first part of paper describes step by step installation of Switched Reluctance Motor & its drive. A special procedure for installation (Mechanical as well as Electrical) is developed in order to reduce acoustic noise, EMI interference and torque ripple of a motor. A serious electrical interference problem is solved using special designed screened cable. The second part of paper describes dy...

Today, Switched Reluctance Motors (SRM) are widely used in research and daily life due to their ability provide large starting torque low manufacturing costs. In terms of kinematics control, the SRM drive system displays high nonlinearity motor structure inverter, which switches between phases operate motor. Most current focuses on controlling without considering caused by inverter. A few studi...
