As friction, intrinsic steady-state nonlinearity poses a challenging dilemma to the control system of 3-DOF (three degree of freedom) flight simulator, a novel hybrid control strategy of nonlinear PID (proportional-integral-derivative) with additional FFC (feed-forward controller) is proposed, and the hardware-in-the-loop simu-lation results are also given. Based on the description of 3-DOF flight simulator, a novel nonlinear PID theory is well introduced. Then a nonlinear PID controller with additional FFC is designed. Subsequently, the loop structure of 3-DOF flight simulator is also designed. Finally, a series of hardware-in-the-loop simulation experiments are undertaken to verify the feasibility and effectiveness of the proposed nonlinear FID controller with additional FFC for 3-DOF flight simulator.
