This.paper reviews.the various.control algorithms.and s.rategies.us.d for fixed-wing morphing aircraft applications. It is.evident from the literature that the development of control algorithms.for morphing aircraft technologies.focus.d on three main areas. The firs. area is.related to precis. control of the s.ape of morphing concepts.for various.flight conditions. The s.cond area is.mainly related to the flight dynamics. s.ability, and control as.ects.of morphing aircraft. The third area deals.mainly with aeroelas.ic control us.ng morphing concepts.either for load alleviation purpos.s.and/or to control the ins.ability boundaries. The des.gn of controllers.for morphing aircraft/wings.is.very challenging due to the large changes.that can occur in the s.ructural, aerodynamic, and inertial characteris.ics. In addition, the type of actuation s.s.em and actuation rate/s.eed can have a s.gnificant effect on the des.gn of s.ch controllers. The aeros.ace community is.in s.rong need of s.ch a critical review es.ecially as.morphing aircraft technologies.move from fundamental res.arch at a low Technology Readines. Level(TRL) to real-life applications. This.critical review aims.to identify res.arch gaps.and propos. future directions. In this.paper, res.arch activities.papers.are categorized according to the control s.rategy us.d. This.ranges.from s.mple Proportional Integral Derivative(PID) controllers.at one end to complex robus. adaptive controllers.and deep learning algorithms.at the other end. This.includes.analytical, computational, and experimental s.udies. In addition, the various.dynamic models.us.d and their fidelities.are highlighted and dis.us.ed.
