Modeling of aero-engine starting process based on rising rate of rotating speed

In this paper, an identification method based on rising rate of rotating speed is proposed. To carry out the dynamic simulation of aero-engine starting process, the proposed modeling method is used to establish the model of aero-engine starting process using the test data collected from starting process and cold running process. The feasibility and efficiency of the proposed modelling method are validated by application to a semi-physical simulation tester. The output accuracy of established model can meet the function and performance requirements for control system in semi-physical simulation tester. The presented modeling method lays an important foundation for design of actual control system.
