Abstract
Considering on precise and rapidly positioning of multi-beam laser, this paper develops a multi-beam laser alignment platform and a beam-target coupling method. The beam-target coupling method is composed of a multi-beam laser spots tracking algorithm and an alignment strategy based on variable structure PI control. With experiments on the multi-beam laser alignment platform, the value of this method is verified.
