Abstract
This paper reviews the various control algorithms and strategies used for fixed-wing mor-phing aircraft applications.It is evident from the literature that the development of control algo-rithms for morphing aircraft technologies focused on three main areas.The first area is related to precise control of the shape of morphing concepts for various flight conditions.The second area is mainly related to the flight dynamics,stability,and control aspects of morphing aircraft.The third area deals mainly with aeroelastic control using morphing concepts either for load alleviation purposes and/or to control the instability boundaries.The design of controllers for morphing air-craft/wings is very challenging due to the large changes that can occur in the structural,aerody-namic,and inertial characteristics.In addition,the type of actuation system and actuation rate/speed can have a significant effect on the design of such controllers.The aerospace community is in strong need of such a critical review especially as morphing aircraft technologies move from fun-damental research at a low Technology Readiness Level(TRL)to real-life applications.This critical review aims to identify research gaps and propose future directions.In this paper,research activi-ties/papers are categorized according to the control strategy used.This ranges from simple Propor-tional Integral Derivative(PID)controllers at one end to complex robust adaptive controllers and deep learning algorithms at the other end.This includes analytical,computational,and experimen-tal studies.In addition,the various dynamic models used and their fidelities are highlighted and dis-cussed.
