| Abstract: | 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. |
