Longitudinal flight control design with handling quality requirements

Robust scheduled control of longitudinal flight with handling quality satisfaction

Design of a Flight Control System in Compliance with Fling and Handling Quality Requirements

 The un-augmented open loop 6-DOF Aerosonde exhibits poor stability and control characteristics in compliance with MIL-F8785C flying quality standards.  As in most classical fixed wing aircrafts, the control inputs to Aerosonde result in pitch, roll and yaw rate responses (rate command characteristics). This has made manual trimming of the UAV, at a given flight condition, with a human pilot-...

Nonlinear Flight Control System Design Including Handling Qualities Evaluation

Progress in aircraft designs heavily depend on automatic flight control system. Modern aircraft have a wide flight envelope (linear and nonlinear) region. This study considers the design of stability and control augmentation system (SCAS) in high angle of attack region for a modern type aircraft via back stepping method. Because of highly nonlinear phenomena in aerodynamic parameters, a locally...

Optimization for Flight Control System with Constraints Supplemented Handling Qualities

In this study, the direct method including evaluation criteria of handling qualities as optimization method’s constraints are carried out to complement problems of the indirect method that assesses whether a flight control system designed by existing optimization techniques satisfies handling qualities or not. For the direct method, co-evolutionary augmented Lagrangian method is used. F-16 long...

Trajectory design and control for aggressive formation flight with quadrotors

In this work we consider the problem of controlling a team of microaerial vehicles moving quickly through a three-dimensional environment while maintaining a tight formation. The formation is specified by a shape matrix that prescribes the relative separations and bearings between the robots. Each robot plans its trajectory independently based on its local information of other robot plans and e...
