In this study, a double-sided linear switched reluctance motor (LSRM) drive was investigated as an alternative actuator for vertical linear transportation applications such as a linear elevator door, hospital and subway doors which move linearly and where accurate position control and rapid response is requested. A prototype sliding elevator door that is focused on a home elevator with LSRMs is...

A switched reluctance motor (SRM) drive generally requires a rotor position sensor for commutation and current control. However, the use of this position sensor increases both cost and size of the motor drive and causes limitations for industrial applications. In this paper, a novel indirect position sensing technique, namely, the sliding-mode observer, is proposed for SRM drives. The correspon...

In this paper, a Switched Reluctance Motor (SRM) drive system is proposed to make trade-off between torque profile and vibration amplitude. the system, power factor correction fast demagnetization are achieved using single-phase Vienna rectifier as front-end converter for SRMs with nominal voltage equal half DC-link voltage. The three-level provides doubled negative in demagnetization, resultin...

Switched Reluctance Motors (SRMs) are increasingly popular machines in electrical drives, whose performances are directly related to their operating conditions. Their dynamic characteristics vary as conditions change. Recently, several methods of the modeling of the magnetic saturation of SRMs have been proposed as analytical functions. However, the SRM system is nonlinear and cannot be adequat...

This study presents the real time hybrid controller implementation for a Switched Reluctance motor Drive. The developed hybrid control law consists of Proportional Integral (PI) controller at steady state, PI-type fuzzy logic controller (FLC) at transient state and a simple logic controller between steady and transient states to achieve desired performance at various operating conditions under ...

SRM has become an attractive alternative in adjustable speed drive due to its simplicity in both motor construction and power converter, and vibration that causes acoustic noise in SRM have generated intense interest from the time it became commercially competitive with dc and ac drives. Basically, there are two conventional ways to reduce the noise: optimize the physical structure of the motor...
