Multi-channel Active Control of Axial Cooling Fan Noise
A multi-channel active control system has been applied to the reduction of free-field tonal noise from a small axial cooling fan, typical of those used in office equipment and other technology. The experimental apparatus consists of an aluminum enclosure which houses the fan, an infrared detector-emitter pair which serves as a reference sensor, loudspeakers, microphones, and appropriate filters...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولFPGA-Based Cooling Fan Control System for Automobile Engine
In this paper FPGA is used as the master chip to design the new fourphase sensorless BLDC(brushless direct current) motor control system of automobile engine cooling fan. The design uses BEMF zero-crossing detection algorithm and the hardware modular design approach, while the open-loop circuit adopted to raise the frequency and voltage and the digital phase-shift circuit based on FIPS algorith...
متن کاملA Double Pipe Heat Exchanger Design and Optimization for Cooling an Alkaline Fuel Cell System
In the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (AFC) (which the electrolyte has cooling role of system) has been considered. Proper control volumes of system with specific qualification have been chosen. Consequently, heat and mass transfer in control volumes have been assessed. Considerations on them and contributed models lead to approve a double tube heat...
متن کاملGlobal active control of axial cooling fan noise: An overview of past and present research
During the past eight years, researchers at Brigham Young University have been engaged in a pragmatic effort to actively reduce the noise radiation from small axial cooling fan noise. The first of a series of studies on the subject demonstrated that a feedforward, multichannel controller with near-field error sensors was successful in globally reducing four harmonics of the blade passage freque...
