20.500.12556/RUL-161648 Modeliranje in krmiljenje kvadrokopterja z uporabo LQR metode v programskem okolju Simulink Modeling and control of a quadcopter using the LQR method in Simulink V okviru magistrske naloge smo modelirali in krmilili kvadrokopter z uporabo LQR metode v programskem okolju Simulink. Model kvadrokopterja smo linearizirali okrog točke lebdenja in ga predstavili v prostoru stanj, nato pa s pomočjo LQR metode določili matriko ojačanj K za linearni model. Enak pristop smo uporabili tudi za nelinearni model. Oba modela smo analizirali z vidika odziva na skočno funkcijo. Na nelinearnem modelu smo primerjali odziv sistema z uporabo LQR metode in PID krmilnika. Krmiljenje je vključevalo rotacije okrog osi x, y in z ter translacijo v z – smeri. Poleg tega smo izvedli identifikacijo ključnih parametrov za modeliranje kvadrokopterja s pomočjo sistema za zajemanje podatkov. Ugotovili smo, da LQR metoda, zasnovana za linearne modele, učinkovito deluje tudi na nelinearnih modelih in da zagotavlja odziv brez prenihaja v primerjavi s PID krmilnikom. In the master's thesis, we modeled and controlled a quadcopter using the LQR method in the Simulink software environment. The quadcopter model was linearized around the hovering point and represented in state space, then the gain matrix K for the linear model was determined using the LQR method. The same approach was applied to the nonlinear model. Both models were analyzed in terms of step response. In the nonlinear model, we compared the system response using the LQR method and the PID controller. Control included rotations around the x, y, and z axes and translation in the z – direction. Additionally, we identified key parameters for modeling the quadcopter using a data acquisition system. We found that the LQR method, designed for linear models, also works on nonlinear models and provides a response without overshoot compared to the PID controller. kvadrokopter LQR algoritem PID krmilnik nelinearen model simulink quadcopter LQR algorithm PID controller nonlinear model simulink true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-09-13 07:31:06 2024-09-13 07:31:14 2024-12-12 10:41:40 0000-00-00 00:00:00 2024 0 0 XX, 55 str. 2024 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 629.014.9:004.021:004.925(043.2) 265721 218749187 37191.pdf 37191.pdf 1 9570EBAE2F200FB3AED3A9291991E645 4820ae1459a567eba5057ea0882195c24c417e3e3f0fa62ab045b773a800d9cd 53fa5a02-7191-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190617 Fakulteta za strojništvo 0 0 0
