Abstract : "In this paper, disturbance rejection algorithm based on model reference adaptive control (MRAC) augmentation
of linear quadratic regulator (LQR) controller is investigated for uncertain turbulence disturbances. The
direct adaptive state feedback optimal controller based on an LDU gain decomposition parameterization is designed
to solve the turbulence compensation problem to enhance control performance. Under the proposed control techniques,
the bounded stability is achieved and the controller is able to remain within tight bounds on the matched
and unmatched uncertainties. Finally, simulation results are presented to illustrate the effectiveness of the proposed
MRAC augmentation of LQR controller."
