Abstract: Considering operating efficiency and flight safety, it is necessary to reduce the Total System Error (TSE) to improve the airspace resource utilization in the terminal area of the air route. During this route segment, Flight Technology Error (FTE) is the main composition. By proposing guidance and control integration design according to accurate tracking problem of four-dimensional trajectory during take-off and landing stage to reduce the flight technology error effectively. Considering the atmosphere turbulence, Loop Transfer Recovery (LTR) has been used to design state observer and optimal control and has realized the flight controller of civil aircraft. Based on that, the adaptive projection operator has been used to estimate the aerodynamic parameter uncertainties in inhomogeneous wind field and the uncertainties have been compensated. Numerical simulations demonstrate that the adaptive controller based on Linear Quadratic Gaussian/Loop Transfer Recovery (LQG/LTR) control technology can restrain the effect caused by uncertainty of aerodynamic parameters and atmospheric turbulence, and an integration controller of four-dimensional trajectory and attitudes for civil aircraft has been achieved.

Key words: future air navigation systems, performance based navigation, flight technology error, trajectory control, integration control, adaptive control
