Abstract

Nowadays, researchers are developing technologies in the aviation industry related to theelectrification of aircraft functional systems. The braking system has a direct impact on the safety,stability and functionality of the aircraft. Therefore, the motivation for replacing the hydraulicsystem is accompanied by the results of comprehensive studies of the architectures of electricbraking systems, including the possibility of improving the quality of such systems through theintroduction of effective control. The work is devoted to the methodology of analytical synthesis ofthe control algorithm for the electric braking system of the aircraft landing gear, as a multiconnectedcontrol object, based on the theory of embedded systems. The mathematical model containsa description of the electrical, mechanical and thermal processes of the system. The require ments for the quality of transients in terms of the angular velocity of the wheel and the temperatureon the surface of the frictional disc are set in the form of restrictions on the settling time and overshootand then transformed into the form of a reference model. The results of computer simulationof the dynamics of the initial and linearized systems, as well as a system with a synthesized regulatorby the full vector of states are shown. The discussion about the robustness of the resulting solutionare presented and the results of computer simulation of a system with a "simplified" regulatorare shown.
