摘　　要：为抑制战斗机急滚过程中的惯性交感力矩和迎角、侧滑角运动耦合,减小滚转过程中各运动的变化范围,在传统比例积分微分(proportional-integral-derivative,PID)控制律设计的基础上,引入自抗扰控制律设计方法,将滚转过程中的惯性交感力矩和运动耦合视为扰动项,进行实时估计并动态补偿。仿真结果显示,飞行品质有效提升,迎角、侧滑角、过载等运动参量变化范围大幅缩小,机动包线大幅扩宽。该方法不改变传统控制律整体架构,具有良好的工程应用价值,对自抗扰控制技术在其他领域的应用具有借鉴意义。In order to narrow the range of motion variation by suppressing inertia coupling moment and motion coupling of angle of attack and angle of sideslip during rapid rolling maneuver of fighter, the active disturbance rejection control(ADRC) law design method is introduced based on the traditional proportional-integralderivative(PID) control law design. The inertia coupling moment and motion coupling during rapid rolling maneuver are regarded as a disturbance, which is estimated in real time and dynamically compensated. The simulation results show that this method can effectively improve the flight quality, greatly narrow the variation range of motion parameters such as angle of attack, angle of sideslip and overload, greatly widen the aircraft maneuver envelope without changing the overall structure of the traditional control law. Therefore, this method has good engineering application value and has reference significance for the application of ADRC technology in other fields.
