摘要
提出用非线性序列二次规划(SQP,Sequen tial Q uadratic P rogramm ing)算法解决发动机性能寻优控制问题。分析了线性规划(LP,L inear P rogramm ing)算法用于发动机性能寻优的固有缺陷以及SQP算法的优点。给出了SQP算法与LP算法用于最大推力模式和最小油耗模式仿真结果对比曲线。数字仿真实验的结果表明,SQP算法具有比LP算法更好的优化效果,在工程实际中有很大的应用潜力。
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.
