For helicopter with large suspension load,the coupling between helicopter body and load will significantly affect the maneuverability and stability of the helicopter. The suspension load swing of helicopter can be induced by the handling of pilot,which leads to the residual oscillation of the helicopter,and the pilot induced oscillation(PIO)phenomenon can be induced by improper hanging of pilot. A certain helicopter is taken as the research object,and the suspension model of helicopter is simplified through some assumptions. A control method oriented to engineering application is proposed. The explicit model-following control method is taken as the infrastructure,and the adaptive control and input-shaping technique are combined to perform the simulation analysis for the control method. The results show that the proposed control method not only can provide the good maneuverability for pilot,but also solve the problem of the residual oscillation of the helicopter.
