摘　　要：由于惯性多余力和电磁多余力的存在,主动侧杆存在杆力误差,特别是主动模式下侧杆受到突加多余力的影响易出现过冲和震荡进而影响飞行安全。为此,提出了一种基于MPC预测模型的系统杆力控制方法。将反馈力作为训练模型,经模型预测出期望反馈力并对不同反馈力做PID调节。通过仿真实验对该控制方法进行验证,结果表明,相比于传统的PID控制算法,所设计的主动侧杆杆力控制方法可有效提升控制精度。Due to the existence of inertial surplus force and electromagnetic surplus force,there are rod force errors in the active side stick.Especially in the active mode,the side stick is prone to overshoot and shock,which will affect the flight safety.In this paper,a method of system stick force control based on MPC prediction model is proposed.The feedback force is used as the training model,and the desired feedback force is predicted by the model,and the different feedback forces are adjusted by PID.The simulation experiment verifies the control method.The results show that,compared with the traditional PID control algorithm,the stick force control method of the active side stick designed in this paper can effectively improve the control accuracy.
