Abstract
The system structure and working principle of the vehicle-mounted line of sight (LOS) stabilization system are introduced. The method for how to eliminate the installation error between the navigation device and turret is proposed, and then two LOS stabilization algorithms of dual-axis servo turret based on coordinate transformation and inverse coordinate transformation are presented, the corresponding control schemes are also given. The accuracy of the algorithm is proved through the successful application of the actual system.
