Apart from further confirmation of the roles of equatorial electrojet (EEJ) and integrated equatorial electrojet (IEEJ) in determining hemispheric extent of EIA crest over higher latitudes, we found some additional roles played by thermospheric meridional neutral wind. Interestingly, the simultaneous observations of EIA crests in both hemispheres of Africa-Middle East showed different morphology compared to that reported over Asia. We also observed interesting latitudinal twin EIA crests domiciled at the low latitudes of the Northern Hemisphere. Our results further showed that weak EEJ strength associated with counter electrojet (CEJ) during sunrise hours could also trigger twin EIA crests over higher latitudes.

Research paper thumbnail of Design and Implementation of Controllers in an Inverted Pendulum

Control of the Inverted Pendulum system in both simulated and physical laboratory is possible as ... more Control of the Inverted Pendulum system in both simulated and physical laboratory is possible as the stability of the system can be attained. Finding or calculating the vectors of gains K using pole placement method and performing the closed loop simulations for the non-linear simulink model with a full state feedback controller of gains calculated makes the implementation possible. The controller is implemented by using the gain calculated on the laboratory physical inverted pendulum system. The stability of the simulated and physical laboratory inverted pendulum system was attained. The variations in time taken for the system to attain the upright position may be due to high K value of gains which make the system approach the stability.
