Abstract

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, Ahead of Print.
To address the strong nonlinearity and time-delay characteristics of micro turbojet engines (MTEs) under dynamic operating conditions, this paper proposes an identification modeling approach that employs the Aquila Optimizer (AO) to jointly optimize the ...
