In high precision control of DC drives, real-time error calculation is the most vital controlling parameter. Due to the time delay of the control circuit, mostly controlling action has been initiated based on the past error that may hamper the precision of the controller. In this regards, future error has to be estimated to initiate the controlling action based on real-time error. But due to the presence...
This paper describes on nonlinear modeling and bifurcation phenomena in switched power-factor-correction (PFC) boost regulator whose switching borders are varying periodically with time. The mathematical modeling is done by nonlinear differential equations. The system dynamics of this switching circuit can be represented by one-dimensional (1-D) piecewise smooth maps under discrete modeling. In particular,...
The advent of rising electrical energy consumption gave rise to a steady increase in the demand on power generation. So, in addition to conventional power generation units a number of renewable energy units are increasingly being integrated into the system. A wind electrical generation system is the most cost competitive of all the environmentally clean and safe renewable energy sources in world....
A Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure or a mis-operation of end user Equipment's. Utility distribution networks, sensitive industrial loads, and critical commercial operations all suffer from various types of outages and service interruptions which can cost significant financial 1oss per incident based on process...
