Reducing torsional oscillation and performance improvement of industrial drives using PI along with additional feedbacks

Torsional oscillations in electrical drive systems with elastic shafts are a well known problem. In the industrial drive systems, a shaft torsional vibration or oscillation is often generated when a motor and a load are connected with a flexible shaft. Large inertias of the motor and load side and a long shaft create an elastic system. The motor speed is different from the load side and the shaft undergoes large...

Locational marginal pricing approach to minimize congestion in restructured power market

The privatization and deregulation of electricity markets has a very large impact on almost all the power systems around the world. Competitive electricity markets are complex systems with many participants who buy and sell electricity. Much of the complexity arises from the limitations of the underlying transmission systems and the fact that supply and demand must be in balance at all times. When the producers and...

Non-polarizing beam splitter and antireflection coating design

The optical coating design of beam splitters and antireflection coatings that are non-polarizing, those that have the same reflection for both “s- and p-polarizations” at specified angles, is a challenge.  This is because the effective indices of refraction for the media and coating layer materials have a different function of the angle of incidence for each polarization. This limits what can be...
