Due to adopting redundant actuation system, force-fight phenomenon appears on aileron’s plane, which would accelerate the fatigue of rudder surface material and loss power. Effective measures must be taken to reduce or eliminate this phenomenon. On the basis of analyzing the control structure of aileron, precisely modeling the control system, and taking system’s nonlinear links into account. The correctness of the model is verified by experiment. Then control strategy of reducing the fighting-force is considered from two aspects of both static and dynamic. The method of using the force equilibrium with pure integral part is to use the integral of each channel’s pressure differential to compensate the displacement control signal; The simulation results show that this method can basically eliminate static fighting-force. In order to reduce the fighting-force during dynamic process at the same time, adopting the PID controller for force equilibrium on the basis of static policy. This method can realize the displacement compensation during the dynamic process. The simulation results show that, after adopting the PID control strategy, the static fighting-force can be eliminated basically, and the dynamic fighting-force can be reduced by about 80%.
