Abstract

Abstract: The turbojet engine is complicated in its starting process and requires collaboration and cooperation involving all the execution structures, thus higher demand is put forward for the control system. How to model the engine starting process, and then accurately describe and analyze the impact of actuator states on engine performance directly affect the engine control system performance. According to the working principle of the JetCat-P400 German turbojet starting process, the rotor speed mathematical model of the turbojet engine starting process is constructed by the component method. The parameters of the model are identified by combining the experimental data of the engine ground test and the voltage data of the actuator. Finally, the start-up process of the turbojet is verified by the time series simulation. The simulation results show that the established engine model can truly reflect the state and the performance of the engine, which is instructive for the engine control system design.
