Altitude Control for Stable Operation of a Geostationary Satellite
Abstract
The objective of the work is to evolve a design based on modeling and simulation of an orbit controller for a satellite orbiting into a particular geo-stationary altitude. This involves a understanding of the system dynamics. Once a satellite is launched in a desired altitude, it
never remains in that same orbit or same altitude. The external forces present in space cause deviations to this particular orbit, to bring back the satellite into the desired altitude. So the altitude should be controlled. Altitude control of a satellite is controlled by controlling PID
parameters. An inappropriate value of altitude can lead the satellite to be fail and fall to the space or earth. This paper mainly discussed about mathematical modeling of a geostationary satellite and deals with altitude of geostationary satellite by means of controller, the PID
controller is used to regulating the altitude from external disturbances. In this paper external disturbances created at altitude 1000 seconds and the error is overcome with PID controller within 400seconds and error minimization in altitude before after PID controller are simulated. In this paper the design concern of altitude is investigated; simulation for designed controller is performed to justify the designed control system as well.
