航空推进系统性能寻优控制的系统模型

System Models of Aviation Propulsion System Performance-seeking Control

航空推进系统性能寻优控制是基于模型的控制技术,各部分采用的系统模型是其关键技术之一。根据性能寻优控制的原理,分析了系统模型选择的原则。详细描述了2部分核心模型:估计模型和性能优化模型。根据寻优控制实时计算的要求,给出了状态变量模型和稳态变量模型的线性化表达式,并介绍了工程实现时模型的使用方法。

Aviation propulsion performance-seeking control was control technology based on the model,the system models adopted of every part were one of its key technologies.The principle chosen by models was analyzed according to the PSC theory.Two kernel models were characterized in details,which were the estimation model and performance optimization model.In terms of the requirement of real-time,the linearized formulations of state variable model and steady-state variable model were obtained,and the models engineering application methods were introduced.
