—The paper presents the design of a nonlinear variable-gain fuzzy controller for a flexible ac transmission systems (FACTS) device like the unified power flow controller (UPFC) to enhance the transient stability performance of power systems. The fuzzy controller uses a numerical consequent rule base of the Takagi–Sugeno type, which can be either linear-or(More)
The next generation of global system for mobile communications/EDGE large signal polar modulation transceivers from RF micro devices (RFMD), Greensboro, NC, is described. The transceiver is realized as a single die in 0.18-mum CMOS. A very low intermediate frequency receiver architecture at 175 kHz is implemented with automatic image calibration. A novel(More)
The next generation of GSM/EDGE large signal polar modulation transceivers from RFMD is described. The transceiver is realized as a single die in 0.18u CMOS. A VLIF receiver architecture at 175 kHz is implemented with automatic image calibration. A novel fractional N offset PLL with digital AFC allows wider bandwidth operation as well as the ability to(More)
This paper presents a particle swarm optimization (PSO)-based neuro-sliding mode controller for the transient stability enhancement of multimachine power systems with unified power flow controller (UPFC). The UPFC is modeled as controllable loads. These controllable parameters are obtained using the sliding mode control (SMC) strategy. A PSO-based single(More)
