Research on Tracking Optimization Strategy of Three-axis Tacking Equipment Based on Particle Swarm Optimization

摘要

Three-axis tracking equipment can solve the question of blind region existing in azimuth -elevation tracking equipment. And it can track the target in the whole-space. However, the relationship of measurement value and space position is more-to-one, which makes for the variety of tracking strategy and the complexity of pilot system. The existing switch strategy restricts the improvement of tracking precision of three-axis tracking equipment. If the current angles and the detect errors are known, the solution of angle increment can be transformed to a question of optimization based on the movement analysis of three-axis tracking equipment. And the angle increment of different initial condition can be solved by particle swarm optimization. The difference of three-axis tracking equipment and azimuth-elevation tracking equipment was analyzed. The validity of this tracking strategy and analytic method was validated by simulation results.
