【摘要】：机载激光通信的视轴稳定是建立激光通信链路的前提。针对通信终端载体的非线性扰动和扰动模型未知造成视轴稳态误差较大的问题,结合自抗扰控制与重复控制,提出了重复控制补偿自抗扰算法,以完全消除周期性稳态跟踪误差。仿真实验结果表明,与自适应PID控制方法相比,重复控制补偿自抗扰算法可以有效抑制平台的非线性扰动,提高了系统的稳态精度,并且具有较快的响应速度与较强的鲁棒性。
[Abstract]:The stability of optical axis of airborne laser communication is the premise of establishing laser communication link. Aiming at the problem of large steady-state error caused by nonlinear disturbance and disturbance model of communication terminal carrier, combined with active disturbance rejection control and repetitive control, a repetitive control compensation algorithm is proposed. The periodic steady-state tracking error is completely eliminated. The simulation results show that compared with the adaptive PID control method, the repetitive control auto-disturbance rejection algorithm can effectively suppress the nonlinear disturbance of the platform, improve the steady-state accuracy of the system, and have faster response speed and stronger robustness.
