development 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 اولAutomatic Gain Control (AGC) circuits
In the early years of radio circuits, fading (defined as slow variations in the amplitude of the received signals) required continuing adjustments in the receiver's gain in order to maintain a relative constant output signal. Such situation led to the design of circuits, which primary ideal function was to maintain a constant signal level at the output, regardless of the signal's variations at ...
متن کاملOptical automatic gain control of EDFA using two oscillating lasers in a single feedback loop
A novel configuration for automatic gain control of optical amplifiers is presented. It uses a F–P filter with 26.7 nm free spectral range and two long-period gratings (LPGs) to produce two lasing wavelengths in a single feedback loop. By bending the LPGs, the cavity losses at different wavelengths can be varied independently to achieve single and two oscillating lasers control conditions. The ...
متن کاملPerformance of optical automatic gain control EDFA with dual-oscillating control lasers
The authors present a simple configuration for dual-oscillating lasers gain control erbium-doped fiber amplifier (EDFA) in which dual-oscillating lasers are formed by two pairs of fiber Bragg gratings (FBGs). Experimental results show that dual-oscillating lasers dramatically reduce steady and transient gain variations caused by spectral hole burning and relaxation oscillations, and the dual-os...
متن کاملAutomatic Gain Control (AGC) in Receivers
AGC was implemented in first radios for the reason of fading propagation (defined as slow variations in the amplitude of the received signals) which required continuing adjustments in the receiver‟s gain in order to maintain a relative constant output signal. Such situation led to the design of circuits, which primary ideal function was to maintain a constant signal level at the output, regardl...
