摘要：The flying of aircraft information necessitates the extension of the theory of formation flight control to allow for three dimensional formation maneuvers. A leader and wingman formation is considered. A rotating reference frame attached to the wingman is used and special attention is given to the motion of the leader relative to the wingman. A thirteen state, three inputs, and three disturbances signal control system which models the dynamics of a two aircraft formation in three dimensional spaces is developed. The theory of formation control was applied to KC-130J tanker and F-16 receiver configuration to study the availability of performing such mission on a large scale. Three formation flight control concepts are investigated. A proportional, integral, and derivative automatic control system to maintain the wing aircraft in the specified formation geometry despite the leader＇s maneuvers is designed, and its performance is examined in simulation experiments. By adding special compensation to each control law to maintain the design damping ratio and gain margin, it is possible to reach the desired performance satisfying the predefined relative distances boundaries.

摘要：Linear Quadratic Regulator （LQR） is modem linear control that is suitable for multivariable state feedback and is known to yield good performance for linear systems or for nonlinear systems where the nonlinear aspects are presented. The fuzzy control is known to have the ability to deal with nonlinearities without having to use advanced mathematics. The LQR integrated fuzzy control （LQRIFC） simultaneously makes use of the good performance of LQR in the region close to switching curve, and the effectiveness of fuzzy control in region away from switching curve. A new analysis of the fuzzy system behavior presented helps to make possible precise integration of LQR features into fuzzy control. The LQRIFC is verified by simulation to suppress the uncertainty instability more effectively than the LQR besides minimizing the time of the mission proposed.
