The Fire Control System Aiming And Stability

In this paper, the decoupling of gun auto-aiming system and the disturbance restrict problem to stabilization system are studied. Firstly, a new decoupling approach to aiming system is presented based on the geometric theory of linear space. Since the varies of gun attitude angle and the vertical vector of the homograph plane are one-to-one, all the elements of modulation gun can be transformed into the calculation of the vertical vector angle, which avoids the calculation accuracy loss of the traditional approach under the condition of the tiny attitude angle disturbance. The simulation states the validity of the approach presented in this paper. Secondly, the stabilizer is designed by using H∞ control theory aiming to the main disturbance of proper motion gun, which can reduce the disturbance effect on the gun-control system to the level of aspiration. This controller of disturbance restrict is satisfying proved by the simulation.
