Self-adjusting fuzzy variable structure control of optical axis stabilization for airborne laser communication

Cao Yang

For the airborne laser communication, optical axis stabilization is the key to keep laser communication link. Conventional coarse tracking controlling method can not effectively overcome the effect of system model parameter change and their influence of uncertainty. According to control requirement, the variable structure controller(VSC) and self-adjusting fuzzy control method was fused, which can force system state to reach sliding surface. Theoretical research and simulation results show it can fully adapt to the disturbance and parameter changes of airborne communication platform. So it has great robustness, and is expected to apply in engineering.
