Design and Control of High Altitude Platform for Communication and Navigation Purpose (original) (raw)
The high altitude platform is designed for navigation and communication purpose. This work focuses on the design and dynamic model of airship that can operate at a height of twenty kilometers above sea level. Significant target of this paper is to propose a coordinating system which can remotely pilot and also has an option of autopilot with auto station keeping. The various control techniques are presented in order to achieve the level flight. First a comprehensive physical and mathematical nonlinear model of the airship is presented and then linearize it by the means of linearization principles. After that, model based control technique such as Linear Feedback Control (LFC), Linear Quadratic Regulator (LQR) and proportional, integral and differential (PID) control are used to achieve level flight of the airship which give robustness against climatic and outer turbulences. With a specific end goal to represent the model based control strategies. The level flight has been accomplish...
