摘　　要：随着高动态飞行器速度和机动性的不断提高,控制系统面临着高非线性、强耦合、快时变、不确定等难题。为提升高动态飞行器过载控制系统的控制精度和稳定性,提出了基于角加速度反馈的自动驾驶仪设计方案,并设计了自抗扰控制系统及其稳定性分析方法。首先,设计了基于角速度和角加速度反馈的PI两回路控制系统方案。然后,基于角加速度反馈设计了自抗扰过载控制方法,并对系统稳定性进行了频域分析。最后,开展了仿真实验研究,结果表明:对于传统的PI过载控制,采用角加速度反馈控制系统的性能明显优于角速度反馈;基于角加速度反馈的自抗扰过载控制系统相比于传统的PI过载控制系统具有更优良的控制效果,显著提升了系统的稳定性和鲁棒性。With the continuous improvement of the velocity and maneuverability of highly dynamic aircraft,the control system is faced with problems such as high nonlinearity,strong coupling,fast time variation,and uncertainty.In order to improve the control accuracy and stability of the high dynamic aircraft overload control system,the autopilot design scheme based on angular acceleration feedback is proposed,and the active disturbance rejection control(ADRC)system and its stability analysis method are designed.Firstly,the PI two-loop autopilot control system scheme based on angular velocity and angular acceleration feedback is designed.Secondly,the ADRC overload control method is designed based on angular acceleration feedback,and the frequency domain analysis of the system stability is performed.Finally,simulation experiments are carried out,and the results show that the performance of the control system with angular acceleration feedback is significantly better than that with angular velocity feedback for the traditional overload control with PI correction.Compared with the traditional overload control system with PI correction,the ADRC system can achieve better control effect,and significantly improves the stability and robustness of the system.
