基于参数空间法的SINS／GPS制导炸弹滚转控制器设计

Design of Roll Control Based on Parameter Space Method for Guided Bomb with SINS/GPS

针对捷联惯性导航/全球定位系统(SINS/GPS)制导炸弹制导控制系统工作特点,利用参数空间方法,设计了各种投弹条件下滚转通道的控制器参数,提出了快速解算控制器参数的拟合方法。然后进行了有初始滚转扰动下的滚转控制数字仿真。仿真结果显示,时频特性均满足给定设计指标,滚转角速度和滚转角在滚转控制器作用下一致收敛,表明该方法有效,可为控制系统设计提供参考。

Based on the analysis of the control system characteristics of guided bomb （GB） with strapdown inertial navigation system（SINS）/global positioning system（GPS）, control parameters of any possible bomb-dropping conditions are obtained by parameter space method, and a fitting method is proposed for computing control parameters fleetly. The simulation is carried out for GB with initial roll disturbing to test control capability. The traits of time-domain and frequency-domain satisfy the given requirements. The rolling rate and rolling angle are uniformly convergent. The efficiency of the above method is confirmed. The method provides valuable basis for the design of control system.
