摘要
针对战术导弹导引头对光轴稳定与目标快速跟踪需求,研究了一种无导引头陀螺的俯仰/偏航式半捷联导引头光学平台稳定技术;该方法利用弹体惯导测量弹体三轴姿态运动,通过控制光学平台的俯仰和偏航两通道伺服系统实现对光轴的惯性空间稳定;设计中考虑到导引头视场、跟踪精度和快速性要求,以及平台框架间的角度耦合、力矩耦合和电机非理想性等约束,通过设计解耦指令分配算法和伺服控制算法实现了对光轴的高精度稳定控制和跟踪;最后通过在Matlab/Simulink环境下的数学建模和仿真,得出无导引头陀螺的俯仰/偏航式半捷联导引头能够实现滚转通道小角度晃动导弹的导引头三轴光学平台稳定。
A non--gyroscope pitch/yaw semi--strapdown seeker optical platform stabilization technology has been proposed for optical axis stability and target fast tracking requirements of tactical missile seeker. The method uses an elastomer triaxial inertial measurement atti- tude motion by controlling the optical platform pitch and yaw servo system to achieve the two--channel optical axis inertial space stability. Taking into account the design seeker FOV, tracking accuracy and fast requirements, as well as the angle coupling between the platform framework, coupling of torque and motor constraints , design the decoupled instruction allocation algorithm and servo control algorithm to a- chieve axis high precision stability control and tracking. Though the mathematical modeling and simulation in Matlab/Simulink , verify that no--gyro pitch/yaw semi--strapdown seeker can achieve optical axis platform stability of small--angle rock roll channel missile seeker .
