Robust adaptive decoupling control of helicopter rotor concordant loading system

The robust adaptive decoupling control method is proposed to the helicopter rotor concordant load system. The controller realized the asymptotic tracking of the desired output trajectory, which used the PID controller as closed-loop controller and used the CMAC neural network to approximate the nonlinear and uncertainties. The stability analyses show that the control method has stability. The main rotor aerodynamic load simulation experiment results demonstrate that the proposed hybrid controller can achieves higher loading spectrum tracking accuracy, and has stronger robust and adaptive to nonlinear and uncertainty of systems.
