【Abstract】 The influence of turntable error and seeker installing error on confidence degree of attitude guidance accuracy in guidance and control system was researched for TV guiding hardware-in-the-loop simulation.Aim to simulation precision of line-of-sight movement,the influences induced by turntable error and seeker installing error were analyzed and the error compensation algorithm was presented.Firstly,the error converting models of adjacent topological order bodies from turntable frame to bomb were built based on the kinematics principle of multi-body system.Then,considering five axes turntable error and seeker installing error,the error model of line-of-sight movement simulating of TV seeker was established.Finally,the error correction algorithm for line-of-sight movement simulating was deduced.The simulations show that the improved algorithm effectively can reduce the error influences of line-of-sight movement induced by turntable error and seeker installing error,improve the simulation precision,and provide the foundation for system optimization design of aerial-to-ground guidance weapon.更多还原
