Applying Model Reference Adaptive Controller for Lateral Motion of Aircraft

Problem statement: This study developed a new application for the outp ut model reference adaptive control of linear continuous systems based on the concepts of hyper-stability. Approach: The main idea is to design a non-linear controller whic h will ensure the minimal error between the reference model and the plant outputs. Results: Therefore, the synthesis of adaptive control with a model of reference was done either using the theory of Lyapunov or from the concept of hyper- stability. The proposed approach was developed and applied to a lateral motion of aircraft, in order t o determine the lateral and directional control angle s required for trim under steady turns and sideslip s. Also, this application is based on the directional and lateral static stability derivatives of the air craft. Conclusion/Recommendations: Simulation results showed the effectiveness of the proposed application method.
