| 摘要: |
| 针对锥形运动对弹体稳定性的影响，建立了导弹锥形运动控制的非线性数学模型，通过引入复攻角的概念，使难以用解析手段处理的非线性模型转换成可解析的一般模型。根据线性化模型分析了导弹复攻角运动方程，推导了制导控制系统参数的稳定控制域范围，分析了控制系统阻尼回路和控制回路对导弹锥形运动稳定性的影响规律，提出了锥形运动控制的稳定性判定方法。仿真结果进一步验证了该判定方法的可行性和正确性，为导弹锥形运动的制导控制系统设计提供了依据。 |

| Abstract: |
| In view of the effect of coning motion on missile stability, a nonlinear mathematical model of missile coning motion control was established. By introducing the concept of complex attack angle, the nonlinear model that was difficult to be resolved by analytical means could be transformed to a general resolvable model. According to the linear model of the missile complex attack angle motion equations, the range of stability control of the guidance and control system parameters were deduced, the influence of damping loop and control loop of control system on the stability of missile coning motion was analyzed, and the method to judge the stability of coning motion control was proposed. Simulation results validate the feasibility and correctness of this method, which provides a reference for the design of missile coning motion of guidance and control system. |
