| Abstract | The paper presents the design phase of the actuators control system development 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 actuations lines control is designed and validated
using a numerical simulation model developed in Matlab/Simulink. The finally adopted control law is a
combination of a bi-positional law and a PI law; the control must behave like a switch between cooling
phase and heating phase, situations where the output current is 0 A, or is controlled by a law of PI type. The
PI controller, for the heating phase, is optimally tuned using the Ziegler-Nichols criterion and the linear
model obtained using the System Identification Toolbox of Matlab. The controlled linearized system for
heating phase is numerically tested in terms of time response, stability, controllability and the observability.
In the actuation control design final phase, numerical simulations, based on SMA non-linear analytical
model, were used for validation. |
