| Morphing wing technology is one of the most efficient approaches to reduce fuel consumption and air pollution. The project, called "CRIAQ MDO 505", was created to explore and evaluate the morphing wing technology. A wing tip system composed of a wing and an aileron was designed and manufactured by the CRIAQ team at the LARCASE. In the context of this project, an optimization approach was studied to improve the aerodynamic performance by changing a wing's shape. Different methodologies were applied to control four internal actuators attached inside the morphing wing. These actuators morph the upper skin of the wing so that the transition region moves from the wing leading edge to its trailing edge.;The research presented here is a part of the MDO 505 project. The aim of this research is to model, simulate and validate the control methods for the wing-tip morphing control system. ANFIS (Adaptive Neuro-Fuzzy Inference System), an adaptive control algorithm, was selected for the morphing wing-tip control. A combination of neural networks and adaptive fuzzy control, ANFIS takes advantage of the fuzzy inference system (FIS) and of the self-learning abilities of the neural network, and thus offers a promising approach for the stability and accuracy of the proposed control system. The simulation and experimental results were acquired using National Instruments (NI) Veristand, Maxon drives and MATLAB/Simulink software. Experimental tests were carried out at the IAR-NRC Wind Tunnel in Ottawa to validate the simulation results. The results showed the potential for applying intelligent control methods to improve the performance of aircraft using morphing wing technology. |
