Abstract

Cilj ovog rada je analiza upravljačkog sustava bespilotne letjelice Aerosonde. Aerosonde je
autonomna bespilotna letjelica s iznimnim svojstvima stabilnosti i upravljanja. Pomoću
Aerosim Blockset-a određen je nelinearni model letjelice. Nelinearni model je uravnotežen i
lineariziran za uzdužno i bočno gibanje. Koristeći linearni model letjelice provedena je analiza
dinamičkih karakteristika uzdužnog i bočnog gibanja letjelice. Analizirana su dva sustava
upravljanja, sustav upravljanja orijentacijom propinjanja u uzdužnom kanalu upravljanja
koristeći linearnu dinamiku uzdužnog gibanja letjelice te sustav bočnog upravljanja i auto
stabilizaciju koristeći linearnu dinamiku bočnog gibanja letjelice. Usporedbom stabilnosti i
upravljivosti letjelice nakon uvođenja upravljačkog sustava sa stabilnosti i upravljivosti
otvorene petlje primjetno je kako upravljački sustav stabilizira letjelicu i omogućava
upravljivost.

Abstract (english)

The objective of this paper is design of a flight control system of Aerosonde unmanned aerial
vehicle. Aerosonde is autonomous aerial vehicle with great stability and control characteristics.
Firstly, the nonlinear 6-degree-of –freedom aircraft is developed using Aerosim
Matlab/Simulink Blockset. Before applying flight control algorithm the nonlinear model is
trimmed and linearized. Using the linearized aircraft model the analyses of aircraft dynamic
characteristics are presented respectively in the longitudinal and lateral-directional senses. Two
flight control systems are analyzed. Longitudinal Rate Command Attitude Hold is analyzed
using the linear longitudinal dynamics. Lateral-Directional Auto-Stabilizer is analyzed using
the linear lateral-directional dynamics. Comparing the stability and control before and after
implement of the flight control system it is easy to notice how flight control manage to establish
stability and control of aircraft.
