摘　　要：针对飞机舵机电动伺服系统存在多余力矩干扰不易抑制的问题,根据系统结构组成及工作原理,建立了数学模型。设计了结合BP神经网络的PID控制器参数整定、角速度前馈与力矩速度反馈的复合控制策略,提高了系统的稳定特性和加载精度。利用MATLAB仿真环境进行了系统动态特性实验。仿真结果表明,该方法不仅能够有效抑制多余力,而且使系统具有良好跟踪效果,完全能够达到控制性能指标的要求。Aiming at the problem that the surplus torque interference of the electric servo system of the aircraft steering system is difficult to suppress, firstly, a mathematical model is established according to the system structure and working principle. Then, on this basis, the composite control strategy is designed, which not only combines the PID controller parameter setting of BP neural network, but also combines the angular velocity feedforward and torque velocity feedback, so as to improve the system stability characteristics and loading accuracy. The dynamics performance of the system is simulated respectively by MATLAB. Simulation results show that the method not only can overcome the surplus torque, but also can achieve good track results, and meet the demand of performance index of the system.
