Analysis is made to tracking and pointing accuracy requirements of the airborne laser weapons the control structure of the compound-axis is given and the error sources of tracking and pointing are concretely analyzed. The compound-axis servo-system was simulated with Matlab/Simulink. The simulation results show that: 1) the system has good dynamic performance high tracking accuracy and fine disturbance suppression effect; and 2) compound-axis of tracking and pointing of the airborne laser weapon is a quite effective control technology.
