Algorithm for Reduction of Force Fight on Airplane Control Surface
 Szásziová, Lenka ; Klusáček, Ondřej (oponent) ; Tomáš, Jan (vedoucí práce)
This thesis is dealing with a new approach to the airplane control system - Distributed Fly-by-Wire System and the resolution will be a part of the research project “Next Generation Distributed Fly-by-Wire System” of company Honeywell - HTS CZ. The aircraft primary surfaces are controlled by two or three electrohydraulical (or electrical) actuators and each actuator is controlled by its independent control unit. The operational tolerances of the system cause small deviations of the input data to the control units and thus each actuator obtains slightly different command. This leads to the mechanical stress of the surface and of the actuators. The main goal of this thesis is to propose an algorithm for a reduction of the force fight on an airplane control surface. The flight control system implementation was analyzed in detail and the Force Fight Algorithm was proposed and implemented in Simulink software. The iterative criterion tuning method was developed to provide the best setting of the algorithm. Finally the impact of Bus time delay on the Force Fight Algorithm was investigated.
