摘　　要：本文针对非传统二维指向镜跟踪系统,建立了跟踪器入射光轴角速率与仪器框架轴角速率的运动学耦合方程,给出了完整跟踪解耦关系式,并对解耦关系式进行了适当的小角度近似和线性化处理,从而实现成像跟踪闭环控制环路。仿真结果验证了解耦关系式的正确性和有效性。经过近似处理后不但有效解决了算法的实时性问题,且对跟踪器镇定时间无较大影响。This paper derives the rate equations for mirror tracking system with unconventional sensor-to-gimbal orientation and a complete decoupled equation is given. Furthermore, a simplified equation and a linearized equation with first order Taylor expansion and rounding are given to be implemented under digital controller. Simulation results show the validity and effectiveness of the given equations.
