This article proposes a new driving method for switched reluctance motor (SRM) by using standard full bridge. The windings in the SRM are connected series to build ring structure, where controllable DC source is inserted. Based on theoretical analysis and calculation made determine control parameters. Besides three-phase SRM, idea can also be applied SRMs with four five phases. compared conventional simulation. results show that method, ripple of torque speed reduces. influence proposed...
Abstract The feeding process of the system in power transmission chain was a high-speed, high impact, non-stationary process, and easy to detect functional faults, aimed at problem, based on nonlinear multi-body dynamics Dubowsky contact modeling theory, gear method including backlash proposed. A dynamic simulation model injected with wear fault established, performance under different levels analyzed. research results show that due teeth, force between teeth increased by about 70%. When...
A proportional integral derivative (PID) controller is most widely applied in control processes, where the delay time always exists. Because of characteristics derivative, which replaced with a filter practical system. Besides parameters PID controller, parameter also required to be tuned. proposed tuning method presented this paper connects and This can for several cases, based on formulas, obtained known time.
FLUENT and ANSYS codes are used to solve the magnethydrodynamics (MHD) equations electromagnetic field equations, respectively. An interface code is developed implement bi-direction transfer of calculation data between ANSYS. Then a 2-D MHD arc model built up with consideration nonlinear ferromagnetic material. The shape, gas flow velocity magnetic distribution presented at current 200 A. influence number splitter plates on motion also analyzed.
The authors contribute a quantitative and systematic model to capture etch non-uniformity in deep reactive ion of MEMS devices. Non-uniformity depends on uneven distributions neutral species at the wafer level, local consumption die level. An synergism is constructed from data obtained several layouts differing layout pattern densities, used predict level variation with an r.m.s. error below 3%. This combined model, which have reported previously based T. Hill et al., (2004), layout. two...
It is known that in order to drive a switched reluctance motor (SRM), the power converter required, which makes it different from other common type of motors such as brushless direct current (BLDC). As result, cost control system for SRM higher than conventional inverter structure BLDC. A new strategy proposed this paper, with an extra DC supply, can be driven by general without changing itself, driving reduced drastically. The method also tested simulation and validation, prove work...
This paper proposes a new driving method for switched reluctance motors (SRMs) using the standard full-bridge inverter. In spite of changing internal structure an SRM, proposed uses extra ring circuit to make it possible inverter drive SRM. Next converter, controllable DC source is needed. With theoretical analysis and calculation, reference value circulating current in was determined proven via simulation. A comparison made with conventional SRM: asymmetric H-bridges. Also, studies were...
In order to reduce the torque ripple of a switched reluctance motor in electric vehicles, space vector pulse width modulation (SVPWM) driving method for (SRM) is proposed. With ring structure, three-phase SRM can be driven by using standard full-bridge power converter instead conventional asymmetric H-bridge. Based on this type topology, an SVPWM applied SRM. The compared H-bridge, results show that effectively. experimental validation also made verify proposed topology and method, which...
Abstract This study proposes a space vector pulse width modulation (SVPWM) driving method for the switched reluctance motor (SRM), which enables use of standard full‐bridge power converter to drive three‐phase SRM with ring structure, in place traditional asymmetric H‐bridge (AHB). Based on this topology, SVPWM approach is employed SRM, and its performance compared that conventional utilising AHB. The findings indicate can effectively reduce torque ripple SRM. Moreover, experimental...
