LQR and LQG control of the helicopter during landing on the ship deck

Purpose The purpose of this study is to test the performance designed automatic control system based on Linear Quadratic Regulator (LQR) and Gaussian (LQG) algorithms during landing helicopter ship deck. This paper a further development series Topczewski et al. (2020). Design/methodology/approach consists two LQR LQG. It integrated with motion prediction autoregressive algorithm parameters calculated using Burg’s method. assumed that source necessary navigation data Inertial Navigation System Global Positioning System. Landing deck performed in way, preselected procedure. Performance analyzed when all available for case one unavailable performing Findings In paper, description developed approach selected procedure presented. Helicopter dynamic model validated manufacturer by pilots, overview Necessary information about also included. Tests showing mission while LQG applied are presented analyzed, taking into account both situations full available/unavailable system. Practical implications Results analyses can be used selection proper methodology prospective helicopters autopilots. Furthermore, analyze safety identified as or incorrect therefore Originality/value dedicated deck, different Influence lack analyzed.
