【摘要】：機(jī)載激光通信的視軸穩(wěn)定是建立激光通信鏈路的前提。針對通信終端載體的非線性擾動和擾動模型未知造成視軸穩(wěn)態(tài)誤差較大的問題,結(jié)合自抗擾控制與重復(fù)控制,提出了重復(fù)控制補(bǔ)償自抗擾算法,以完全消除周期性穩(wěn)態(tài)跟蹤誤差。仿真實(shí)驗(yàn)結(jié)果表明,與自適應(yīng)PID控制方法相比,重復(fù)控制補(bǔ)償自抗擾算法可以有效抑制平臺的非線性擾動,提高了系統(tǒng)的穩(wěn)態(tài)精度,并且具有較快的響應(yīng)速度與較強(qiáng)的魯棒性。
[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.
