Ibis paper investigates the application of fuzzy algorithm for the speed control of switched reluctance motor (SRM) drives. For the purpose of performance simulation of closed loop SRM drive, its components are modelled in a systematic manner. Hysteresis current controlled midpoint converter is employed to feed four phase 8/6 SRM. Non-linearity caused by magnetic saturation in the motor is also...

Simple power electronic drive circuit and fault tolerance of converter are specific advantages of SRM drives, but excessive torque ripple has limited their use to special applications. It is well known that controlling the current shape adequately can minimize the torque ripple. This paper presents a new method for shaping the motor currents to minimize the torque ripple, using a neuro-fuzzy co...

Simple power electronic drive circuit and fault tolerance of converter are specific advantages of SRM drives, but excessive torque ripple has limited its application. This paper presents a novel method of controlling the motor currents to minimize the torque ripple, using a neuro-fuzzy compensator. In the proposed control concept, a compensating signal is added to the output of a classical PI c...

In this paper, we propose a right-to-left dependency grammar parsing method for languages in which a governor appears after its modiier like Korean and Japanese. Unlike conventional left-to-right parsers, this parsing method can take advantage of the governor post-positioning property of such languages to reduce the size of search space by using the idea of a headable path. A headable path is a...

as, the terrorism, nowadays, is an important and effective matter that affects different problems especially national security, it is tried to study an important aspect of interaction fields between national security and political development in developing countries and iran. an important point in this study is to consider terrorism as an strategic phenomenon that follows the procedures includi...

Metabolic reprogramming in stromal cells plays an essential role in regulating tumour growth. The metabolic activities of tumour-associated macrophages (TAMs) in colorectal cancer (CRC) are incompletely characterized. Here, we identify TAM-derived factors and their roles in the development of CRC. We demonstrate that ABHD5, a lipolytic co-activator, is ectopically expressed in CRC-associated ma...

This paper presents a novel adaptive reference governor for robust tracking control in constrained linear systems with bounded disturbances. The proposed reference governor achieves a performance improvement over the existing reference governors by virtue of its added feature: adaptability. The design of such an adaptive reference governor involves a nonlinear non-deterministic polynomial time ...

The paper addresses the problem of vehicle rollover avoidance using reference governors applied to modify the driver steering input in vehicles with an active steering system. Several reference governor designs are presented and tested with a detailed nonlinear simulation model. The vehicle dynamics are highly nonlinear for large steering angles, including the conditions where the vehicle appro...

this paper presents  the  levels  of total  mercury  (t-hg)  in  dorsal  muscle,  liver  and  spleen of pike  (esox lucius) from  anzali  lagoon  in iran.  sampling were  carried  out from  july  2004 to july 2005. in addition 78 samples were collected. t-hg concentration  were  calculated  in relation to biometric factors. t-hg was measured by the leco ama 254 advanced mercury analyzer (usa) a...

Systematic Review methodology (SRm) is an increasingly popular choice for literature reviews in the Social Sciences. Although, compared to traditional narrative reviews SRm appears timeconsuming and laborious, transparency and replicability of the methodology is argued to facilitate greater clarity of review. Nevertheless, researchers in Industrial, Work and Organizational (IWO) Psychology have...
