Modeling and simulation of longitudinal autopilot for general aviation aircraft

From the dawn of advanced aerospace technology, the aspect of stability and automated control is an important field of research interest providing ease of handling and friendly assistance for piloting. Considering this challenging aspect, development of automated control system is chosen for this research. The aim of this paper is to design a longitudinal autopilot for a general aviation aircraft and to analysis the performance of the developed model both for normal condition and atmospheric disturbance. To improve the overall performance, stability of the system and to overcome the atmospheric disturbance a compensator along with a PID controller has been designed. Simulation results of MATLAB Simulink have been also analyzed.
