Abstract

It is considered aircraft both velocity and flight altitude adaptive control algorithm, based on the reverse flight dynamics approach.
The main control goal consists in the providing needed values both aircraft flight velocity and altitude due to engine and altitude actuators simultaneous control actions.
Integrated engine control system of AN-124Ruslan aircraft applying to typical cruise flight mode is given as an example of mentioned approach utilization. The integration of engine and flight altitude control allows to met all contradictory requirements to engine control system of the discussing aircraft.
The following engine operation mathematical model has been used for discussing algorithm creation:

where is relative value of engine compressor rotation velocity.
Mathematical simulation has been performed in order to analyze developed algorithm performances. Simulation results are given, which demonstrate algorithm operability and efficiency in presence of the uncontrollable factors.
Developed integrated control algorithm provides increasing operation speed of both velocity and flight altitude control loops as well as reducing fuel consumptions due to flight altitude optimization.
So, suggested approach can be used for prospective thrust control algorithmc development.

Keywords:

adaptive algorithm, the integrated management, the draught automatic machine, power- plant
