This paper presents a practical design of an intelligent type of controller using polynomial neural network (PNN) concepts for excitation control of a practical power generating system. This type of controller is suitable for real time operation and aims to improve the dynamic characteristics of the generating unit by acting properly on its original(More)
Simulation, design and prototype construction of a low cost three phase permanent magnet (PM) brushless DC (BLDC) motor controller for low power applications is studied in this paper. The drive circuitry is based on the PIC16F877A microcontroller (μC), which –among othersperforms pulse width modulation (PWM) control for a 6-step, 120-degree trapezoidal PM(More)
Currently, the electric power industry is in transition from vertically integrated utilities to an industry that will incorporate competitive companies. This increases the complexity of the load frequency issue and calls for more insight and research. In this context, the tuning of a two-area AGC system after deregulation is not yet discussed and is studied(More)
