Design of an Adaptive Controller for a Remotely Operated Air Vehicle

Influence of flight control law on spin dynamics of aerodynamically asymmetric aircraft

“…Moreover, problems may also be faced when scheduling with respect to rapidly changing state variables (Gill et al, 2015). To overcome such limitations, nonlinear control law designs such as dynamic inversion (Slotine and Li, 1991) and various adaptive techniques (Crespo et al, 2012) may be tested with the aircraft flight simulation model for obtaining further improvements in dynamical characteristics of the aircraft spin.…”

Nonlinear Dynamics of Aircraft Controller Characteristics Outside the Standard Flight Envelope

“…[14] and, for the fixed-gain controller, Ref. [7] where it is refereed to as the 'baseline controller'. The system dynamics can be represented aṡ…”

“…Based on the saturation limits, the integrator anti-windup strategy proposed in [7] is applied to the ⟨e α , δ e ⟩ pair.…”

“…Also, care needs to be exercised when scheduling with respect to a state variable that changes rapidly. To overcome the limitations of linearity, much work has been done on nonlinear control law design, such as by dynamic inversion [5] and a host of adaptive techniques [6,7]. These are also not necessarily problem-free, with issues such as robustness to model uncertainty and stability guarantees requiring special attention.…”

Upset Dynamics of an Airliner Model: A Nonlinear Bifurcation Analysis

“…It allows the development of control laws that can be implemented in real time on the GTM in-flight model. Much of the GTM research has been on the development of controllers [13,14] to help prevent upset scenarios and for implementing into the Aircraft Integrated Resilient Safety Assurance and Failsafe Enhancement (AIRSAFE) concept, where resilient control is integrated with flight safety assessment and management; an overview is given in Ref. [15].…”
