| Abstract: | A methodology based on the nonlinear algorithm of Sequential Quadratic Programming(SQP) in aero-engine performance seeking control was presented.This article is aimed at analyzing the inherent limitation of Linear Programming used for aero-engine performance seeking control and to solve the problem of aero-engine performance optimization using nonlinear SQP method.The results of numerical simulations of maximum thrust mode and minimum fuel consumption mode using SQP and LP respectively show that SQP algorithm has better optimization result than LP algorithm.SQP algorithm has great application potential in engineering. |
