AbstractThis chapter presents the design and the validation of the actuators control system for a morphing wing application. Some smart materials, like Shape Memory Alloy (SMA), are used as actuators to modify the upper surface of the wing made of a flexible skin. The finally adopted control law is a combination of a bi-positional law and a PI law. The controller is validated in two experimental ways: bench test and wind tunnel test. All optimized airfoil cases, used in the design phase, are converted into actuators vertical displacements which are used as inputs reference for the controller. In the wind tunnel tests a comparative study is realized around of the transition point position for the reference airfoil and for each optimized airfoil. © 2011 Springer-Verlag Berlin Heidelberg.
