Aimed at the above problems, the hardware structure and working principle of the system are introduced, and the mathematical model of the system is established. On this basis, the generation mechanism and working characteristics of nonlinear interference are analyzed. According to the research of nonlinear interference suppression methods in the field of loading system, the structure and control are also summarized and classified, and the performance is compared and the applicability is analyzed. As to the problem of the suppression of extra torque, a model predictive control scheme is proposed to compensate the extra torque. Experimental results show that the command torque can be tracked accurately, the error rate is less than 1.93%, and the excess torque elimination rate is up to 95.86%. The effectiveness of the proposed scheme is proved, which can improve the suppression ability of extra torque and increase the tracking accuracy of the system. 電動(dòng)加載系統；非線(xiàn)性干擾；多余力矩；模型預測控制；抑制；飛機舵機 electric loading system; nonlinear interference; extra torque; model predictive control; suppression; aircraft rudder 劉曉琳,王靜 中國民航大學(xué)電子信息與自動(dòng)化學(xué)院 jsjclykz/article/abstract/202306020616
