Integrated Flight / Propulsion System H ¡Þ Controller Design

This paper designed a multivariable robust controller based on the hybrid sensitivity Hxapproach for a certain civil fighterand a certain civil turbine-fan engine .The main work is the study of the reliability control problem of the ordinate movement of the Integrated Flight/Propulsion Control System. The main content of this dissertation are as follows: The ordinate movement, fighter model is built based on the special fighter data. Some tests have been made on a certain state; A special control system for this fighter is built based on the data offered .Then the control system and the fighter model are connected to get the Integrated fighter system . The results show that the Integrated system is reliable on the special design state. Based on the engine program offered, the engine model was built and tested on a special state point. Using the fighter and the engine model bu i It, the Integrated system model was btii It based on the relationship of the two models . The feedback control system based on hybrid sensitivity Hx approach was designed for the Integrated system, and its Hx robustness, anti-rejection and reliability are analyzed. The results show that the Hybrid sensitivity control system is very good on the Hx robustness, anti-rejection and reliability.Finally, the simulation of the Integrated Flight/Propulsion Control System show that the Integrated Flight/Propulsion Control System based on the hybrid sensitivity //Bapproach has resulted animprovement on this system. Because during the design of the feedback system, the relationship and coupling between the propulsion system and the flight system were taken into consideration, the Integrated Flight/Propulsion Control System designed can improve the performance of the airplane, reduce the burden of the pilot and satisfy the requirement of the Integrated control system...
