For the decoupling control of helicopters with input saturation, an improved information fusion decoupling control algorithm is proposed. By fusing the soft constraints information of the desired output and the control energy of the main channel and the relevant coupling channels, with the hard constraints information supplied by the system state equation and the output equation, the optimal estimation of the decoupling control rule under the quadratic performance index can be obtained, and the dynamic characteristics and decoupling performance of the inner control loop of the helicopters can be improved. By adaptively adjusting the soft constraints information of the control energy, the control variables satisfied the limitation requirements of input saturation, and avoid the decoupling performance deterioration and the driver overload caused by input saturation. The proposed information fusion control algorithm based on discrete model of the controlled system, and could be easily applied to engineering practice. The simulation results demonstrate the effectiveness of the proposed method.
