Compound-axis macro-micro control and modeling of laser weapon tracking system

针对激光武器跟瞄系统的高精度要求和脱靶量时滞问题,阐述了复合轴宏、微控制的基本原理。分析了机动目标的等加加速度模型。建立了基于Kalman预报器的激光武器跟瞄系统的复合轴宏、微控制。以等效正弦运动和匀速直线运动为例进行了仿真。结果表明,复合轴宏、微控制比单检测器控制的精度更高,而且宏、微控制系统的控制过程比较简单,适于工程实现。

In the light of the problems concerning high-precision demand and miss-the-target time delay in the laser weapon tracking system（LWTS）, the basic principles of the compound-axis macro-micro control（CAMMC） were expounded. The three derivatives model of maneuvering target was analyzed. A CAMMC system was constructed for LWTS based on Kalman predictor. Taking the equivalent sinusoidal movement and the uniform linear movement as examples, the system was simulated. The results showed that the precision of the CAMMC is higher than that of singel-detector control, and the CAMMC system is simple and suitable for engineering implementation.
