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 اولAn improved hysteretic PWM control with feed-forward and feedback
In this paper, an improved hysteretic PWM control with feed-forward and feedback for the buck converter is presented. The proposed control method is based on hysteretic control of capacitor C voltage, which not only offers faster transient response to meet the challenges of the power supply requirements of fast dynamic input and load changes, but also provides better stability and solves the co...
متن کاملFast Frequency Acquisition Phase Frequency Detector with Minimal Dead Zone for High Frequency Phase Lock Loop
This paper introduces a new-type Phase-Frequency Detector (PFD) for Charge-Pump based Phase-Looked-loops (CPPLLs). Dead zone in a phase-frequency detector reduces the input detection range and make worse cycle slips. This brief analyzes the blind zone in latch-based PFDs and proposes a technique that removes the blind zone caused by the pre-charge time of the internal nodes. With the proposed t...
متن کاملA Modified Structure for Feed Forward Active Noise Control Systems with Improved Performance
Several approaches have been introduced in literature for active noise control (ANC) systems. Since FxLMS algorithm appears to be the best choice as a controller filter, researchers tend to improve performance of ANC systems by enhancing and modifying this algorithm. In this paper, the existing FxLMS algorithm is modified which provides a new structure for improving the noise reduction and conv...
متن کاملLoad Frequency Control Based on Improved Fuzzy Controller in the Microgrid with Thermoelectric Generator
The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....
