摘　　要：针对飞机舵机电动加载系统存在舵机与加载电机耦合所造成的多余力矩扰动问题,以无刷直流电机作为加载机构,构建系统数学模型,并提出一种基于鲸鱼优化算法(whale optimization algorithm,WOA)的内环电机速度控制、外环力矩控制的双环复合控制策略。在电机速度环控制中,结合Skew Tent混沌映射、动态搜索因子并改进适应度函数设计基于改进型WOA的零基准自抗扰控制器(active disturbance rejection control,ADRC),利用改进型WOA实现零基准ADRC的参数寻优;在力矩环控制中,设计带有补偿环节的重复PID控制器。仿真结果表明,改进型WOA具有良好的寻优能力,且基于此的双环复合控制策略能够有效提高系统跟踪能力并能明显抑制多余力矩。For the problem of extraneous torque caused by the coupling between the rudder and the loading motor in an aircraft rudder electric loading system,a brushless direct current motor was used as loading mechanism to establish a mathematical model and a double loop composite control strategy based on whale optimization algorithm(WOA)combining a motor speed control inner loop and a torque control outer loop was proposed.In the motor speed loop control,zero active disturbance rejection control(ADRC)based on the improved WOA that was used to optimize the parameters of zero ADRC was designed by combining Skew Tent chaotic mapping,a dynamic search factor and an improved fitness function;in the torque loop control,a repetitive PID controller with a compensator was designed.The simulation results show that the improved WOA have good optimized ability,based on which,a,double loop composite controller can significantly improve tracking ability and suppress extraneous torque.
