为了研究多轴多框架光电稳瞄系统的稳定精度并且避免推导其复杂的动力学微分方程, 提出了利用Matlab和ADAMS进行光电稳瞄系统结构控制联合仿真的方法。研究了联合仿真模型的方位轴和俯仰轴单位阶跃响应, 和在不同方向的随机线振动下的瞄准线惯性角速率, 以及在2°、1Hz不同方向角扰动下瞄准线的稳定精度。仿真结果与理论定性分析吻合, 表明联合仿真方法可行,可用于后续产品的开发。

To study the stabilization precision and avoid deducing the complicate dynamic equation of multi-gimbal electro-optic stabilization system, a method for structure-control co-simulation using Matlab and ADAMS was developed. The step response of azimuth and elevation axes, the line-of-sight(LOS) angular velocity in inertial space under tri-axis base linear vibration ,and the LOS stabilization precision under tri-axis base angular motion of 2° and 1 Hz were studied. The simulation results and the qualitative analysis are consistent, indicating that the method is useful and can be applied for new product development.
