摘　　要：针对飞机舵机电动加载系统的力矩跟踪和干扰抑制的优化问题,提出一种基于单神经元和扰动前馈抑制的电动加载复合控制方法。首先利用改进的粒子群算法调整单神经元PID控制器的参数和系数K,然后对舵机角位移进行前馈补偿来抑制多余力矩,以减小舵机位置干扰对系统的影响;最后对电动加载复合控制系统进行仿真。仿真结果表明,系统的抗干扰能力及加载精度得到进一步提高,证明了该复合控制方法在理论上的可行性。A kind of composite control method based on single neuron and feedforward disturbance rejection was presented to solve the torque tracking and disturbance rejection of the electric loading system of aircraft rudder. Firstly, an improved particle swarm optimization was used to determine the parameters and coefficient K of the single neuron PID controller, and then the rudder angle displacement of feed-forward compensation was used to restrain extra torque, so as to reduce the actuator position disturbances; finally had a simulation of the electric load control system. The simulation results show that, the anti- interference ability and precision of loading system have been further improved, and the composite control method is feasibility in theory.
