Design of UAV Longitudinal Regulator System Stability Due to Turbulence on Cloud Seeding Operation: A Case Study of Wulung PA-07

摘要

UAV longitudinal regulator stability algorithm of Wulung PA-07 has been designed using Simulink/Matlab. This regulator system is design using pole placement method in order to againts the disturbance caused by turbulence. The Dryden wind turbulence model is used to represent the real atmospheric disturbance. By using pole placement approach, the system can stand on high turbulence with maximum normal velocity deviation 0.59 m/s and pitch angle 0.182°. The damping ratio and natural frequency of the system are ζ = 0.5, ω_n = 0.398 rad/s and ζ = 0.564, ω_n = 0.394 rad/s for phugoid mode, while ζ = 0.699 and ω_n = 5.55 rad/s for short period mode.
