A Fuzzy Theory-Based Control of a Chopper-Controlled Converter DC Machine Drive
Abstract: A fuzzy controller is designed for closed loop control of Chopper controlled generator load coupled separately excited DC motor and presented in this paper. This system has been designed to have two loops with an inner fuzzy current controller and an outer fuzzy speed controller. A linear model of closed loop system is developed by using small perturbation technique including the effect of generator load, the armature reaction and the …

Digital Communication Receiver CMOS Chip Design
Abstract: RF receivers are such electronic devices that discrete radio signals from one another and transform specific signals into respective audio, video, or data formats. It uses an antenna to receive transmitted radio signals and a tuner to separate a specific signal from all of the other signals that the antenna receives. Detectors or demodulators at that moment extract information that was programmed formerly to transmission. There are numerous customs to …
