Enhanced Pitch Angle of Aircraft System Using Fractional Model Reference Adaptive Control Approach

Abstract

Fractional calculus has been rediscovered by scientists and engineers in the last two decades and applied in an increasing number of fields, namely in the area of control theory. FMRAC (Fractional Model Reference Adaptive Control) is an advanced control strategy that extends traditional adaptive control techniques by incorporating fractional calculus. This approach is particularly beneficial in systems where dynamics are complex and exhibit non-integer order behavior. The current research work presents the use the fractional Model Reference  adaptive control  (FMRAC) approach to improve the performances (rise time, setting time , overshoot and mean absolute error)  for Aircraft by introducing fractional order integrator in the model reference system. To validate the arguments, effectiveness and performances analysis of the proposed FMRAC algorithm have been studied in comparison to the classical MRAC approach.   Numerical simulation and analysis are presented to verify the best controller. The FMRAC approach gives the best results in terms of settling time, rise time, overshoot and mean absolute error. This approach can also be generalized to others  fractional and integer systems in order to improve their performances and noise rejection.
