摘要

针对激光通信对光束跟踪高响应速度与宽控制带宽的严苛需求，研究了基于模型参考自适应控制（MRAC）的快速反射镜（FSM）位置跟踪方法。通过建立音圈电机驱动FSM的模型，设计无超调、大带宽的参考模型，并基于Lyapunov稳定性理论，推导其自适应律，保证了系统动态跟踪能力。结果表明：在阶跃响应中，MRAC调节时间为0.88ms，相比同等带宽PID控制缩短45.3%，且均无超调；在300Hz正弦跟踪中，MRAC相位延迟31.3°和幅值误差11%均优于PID控制；在扫描工况模拟中，MRAC稳速时间2.8ms较PID缩短38%。因此本文提出的方法有效解决了FSM在激光通信应用中的高动态跟踪难题，具备响应速度快、跟踪带宽大的优势，同时通过理论推导的自适应律降低了参数整定复杂度，具有较好的工程应用前景。

Abstract

To address the stringent requirements of high response speed and wide control bandwidth for beam tracking in laser communication

a fast steering mirror(FSM)position tracking method based on model reference adaptive control(MRAC)is investigated.By establishing a model of the voice coil motor-driven FSM

a reference model with no overshoot and large bandwidth is designed

and the adaptive law is derived based on Lyapunov stability theory

which ensures the dynamic tracking capability of the system.The results show that in step response

the MRAC settling time is 0.88ms

which is 45.3% shorter than that of PID control with the same bandwidth

and both methods have no overshoot.In the 300Hz sinusoidal tracking

MRAC achieves a phase delay of 31.3° and an amplitude error of 11%

which are both superior to those of PID control.In the simulated scanning working conditions

the speed-stabilization time of MRAC is 2.8ms

which is 38% shorter than that of PID.Therefore

the proposed method effectively addresses the high-dynamic tracking challenges of FSM in laser communication applications

with the advantages of fast response speed and wide tracking bandwidth.Meanwhile

the adaptive law derived through theoretical deduction reduces the complexity of parameter tuning

demonstrating good prospects for engineering application.
