Vibration Control of Flexible Spacecraft Using Adaptive Controller

The aim is to develop vibration control of flexible spacecraft by adaptive controller. A case study will be carried out which simulates planar motion of flexible spacecraft as a coupled hybrid dynamics of rigid body motion and the flexible arm vibration. The notch filter and adaptive vibration controller, which updates filter and controller parameters continuously from the sensor measurement, are implemented in the real time control. The least mean square algorithm using the adaptive notch filter is applied to the flexible spacecraft. This study will show that the adaptive vibration controller successfully stabilizes the uncertain and it will accurately control the vibration of flexible spacecraft. The Least mean square  algorithm is applied in flexible spacecraft to attenuate the vibration. The simulation studies are carried out in a Matlab/Simulink environment

Optimization and Life cycle Cost Analysis of Renewable Energy Supply Options for Academic Buildings- A Case Study

In this paper focuses on realizing alternate power supply sources to the Academic buildings located at Manipal, Karnataka. India, and analyzing the possible combination of the Hybrid Energy sources. The main emphasis is on steering the Optimization and Life Cycle Cost (LCC) analysis of the Hybrid Energy sources. The Hybrid Energy System optimization and feasibility study are carried out using HOMER Software and the results are verified with Linear Programming. The case study is conducted with the involvement of PV, Wind turbine and Diesel Generator (DG) along with the battery bank. Further, the DG was integrated with the renewable energy sources to smoothen the power circulation and enhance the reliability issues. The realistic climate data obtained from the NASA website for the location Manipal (13.347° N, 74.75° E) and estimates the solar and wind power using the models developed Keywords: PV, Wind, LCC, Optimization, HOMER JEL Classifications: Q21, Q40, Q41 DOI: https://doi.org/10.32479/ijeep.789
