Abstract. The present work illustrates an application of shape memory alloys and nonlinear controller applied to the active angular control of a sectioned airfoil. The main objective of the proposed control system is to modify the shape of the profile based on a reference angle. The change of the sectioned airfoil angle is resultant by the effect of shape memory of the alloy due to heating of the wire caused by an electric current that changes its temperature by Joule effect. Considering the presence of plant's nonlinear effects, especially in the mathematical model of the alloy, this work proposes the application of an on-off control system.

“…"morphing aircraft". Considering the drag reduction, fuel consumption economy and flight envelope increasing promising benefits, many universities, R&D institutions and industry initiated and developed morphing aircrafts studies in the last decade (Munday and Jacob, 2002;Sanders, 2003;Manzo et al, 2004;Skillen and Crossley, 2005;Bornengo et al, 2005;Moorhouse et al, 2006;Namgoong et al, 2006;Namgoong et al, 2007;Seigler et al, 2007;Gamboa et al, 2009;Baldelli at al., 2008;Inoyama et al, 2008;Thill et al, 2008;Perera and Guo, 2009;Bilgen et al, 2009;Bilgen et al, 2010;Thill et al, 2010;Seber and Sakarya, 2010;Wildschek et al, 2010;Ahmed et al, 2011). The multidisciplinary aspects involved by such studies, bring together research teams in many fields of the science: aerodynamics and aeroelasticity, automation, electrical engineering, materials engineering, control and software engineering.…”

Fuzzy Controllers -Recent Advances in Theory and Applications 2 material actuators and pressure sensors. The aim of these studies is to develop an automatic system that, based on the information related to the pressure distribution along the wing chord, moves the transition point from the laminar to the turbulent regime closer to the trailing edge in order to obtain a larger laminar flow region, and, as a consequence, a drag reduction.The objective of the research presented here is to develop a new morphing mechanism using smart materials such as Shape Memory Alloy (SMA) as actuators and fuzzy logic techniques. These smart actuators deform the upper wing surface, made of a flexible skin, so that the laminar-to-turbulent transition point moves closer to the wing trailing edge. The ultimate goal of this research project is to achieve drag reduction as a function of flow condition by changing the wing shape. The transition location detection is based on pressure signals measured by optical and Kulite sensors installed on the upper wing flexible surface. Depending on the project evolution phase, two architectures are considered for the morphing system: open loop and closed loop. The difference between these two architectures is their use of the transition point as a feedback signal. This research work was a part of a morphing wing project developed by the Ecole de Technologie Supérieure in Montréal, Canada, in collaboration with the Ecole Polytechnique in Montréal and the

“…Mueller 4 provides an excellent compendium of papers for some of the work done in this area until the beginning of the 21st century. Seigler et al, 5 Sanders et al, 6 Bowman et al, 7 Tidwell et al, 8 Bye and McClure, 9 Abdulrahim and Lind 10 are among several of the papers in the last decade that discuss various aspects of morphing aircraft. Costello and Webb 11 demonstrated that articulated wing MAVs, hinged at the root, could reduce gust sensitivity.…”

This paper explores the use of variable wing dihedral and variable wing twist (in conjunction with a conventional horizontal elevator) to control an aircraft performing a perching maneuver. A choice of controller architecture wherein the dihedral is employed in the forward path and the elevator and twist are employed in the feedback path, is considered. The aircraft is modeled as a multivariable linear time-varying system. A specific perching trajectory is considered; and the open-loop aircraft is longitudinally unstable for a segment of this perching trajectory and lateral-directionally unstable for the entire perching trajectory. A multivariable time-varying controller is designed to efficiently stabilize the aircraft as well as reject longitudinal-lateral-directional wind disturbances, while closely tracking the reference perching trajectory.
