Abstract

An improved composite control algorithm to improve the pointing accuracy of a Acquiring

Tracking and Pointing(ATP) system in a satellite platform was presented for controlling a fast-steering-mirror to reduce the beam jitter. The advantages of the composite control combined an adaptive feedforward algorithm and a PID feedback algorithm were analyzed according to the two algorithms characteristics. Then

the convergence problem of direct composite control of two algorithms was analyzed and solved by introducing a new algorithm

decoupling composite control using decoupling theory. Finally

the algorithms referred above were experimented and compared. Experimental results indicate that

in the experiment conditions

the control accuracy of the decoupling composite control algorithm is nearly 10 times better than that of the classic PID control algorithm and 3 times better than that of the adaptive feedforward algorithm

respectively.It concludes that the decoupling composite control algorithm combines the merits of two algorithms and can reduce the beam jitter better.
