Abstract

The unsteady and non-linear helicopter model of UH-60A was established

while the non-linear integrated helicopter/engine model was also constructed.Then

an augmented linear quadratic regulator(ALQR) method for the flight controller was designed.Simulative experiments on the integrated helicopter/engine model were conducted.Numerical simulation results and the comparison with H∞ controller demonstrate that the ALQR flight controller had its superiority of decoupling

command tracking and robustness.In addition

it was also found that the closed-loop system of engine could satisfy the need of power required by the helicopter in usual task

and the power turbine speed could meet the requirement of ADS-33E.
