Abstract

A disturbance compensation scheme based on a piezo-electric steering control system was presented

for the vibration of a satellite platform seriously impacted the tracking and pointing accuracy in space optical communication. A mathematical model for the piezo-electric steering system was built. Then

an adaptive controller based on an improved Least Mean Square(LMS) filter was designed

and effect factors on optimal step length choices were analyzed. For the problem of signal phase delay

an adaptive delay filter was designed not only to compensate the phase delay

but also adaptively to adjust the input signal phase to increase its convergence rate without adding the step length. Finally

a verifying experiment was performed.The results show that the remained errors after compensation are rad magnitude and the compensation factor is over 85%.These results prove that this control scheme is valid and feasible.
