【摘要】 本文研究了自行火炮操瞄解耦和稳定系统的扰动抑制问题。首先，基于线性空间的几何理论，提出了一种新的操瞄系统解耦方案。由于火炮姿态角变化与相应平面的法向量是一一对应的，从而可将调炮诸元转化为法向量夹角来计算，这样可避免传统方案在微小姿态角扰动情形下导致的计算精度可能的损失。作者所做的仿真也表明了文中所提方案的有效性。其次，针对行进中自行火炮的主要干扰源，利用H_∞。控制理论，设计了稳定系统的镇定控制器，可将扰动对系统的影响降低到期望的水平。通过仿真实验，这种扰动抑制控制器具有满意的控制效果。更多还原

【Abstract】 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.更多还原
