半捷联位标器安装在弹体上,由于寄生回路的存在,使得位标器稳定跟踪控制回路和弹体姿态控制回路产生严重耦合,影响了位标器的稳定与跟踪。针对半捷联导引头稳定平台的稳定与跟踪问题,提出了一种半捷联位标器稳定跟踪控制与弹体姿态控制的一体化方法。基于反步控制原理设计了控制律,通过合理选择反馈增益可保证系统的稳定性与动态性能。最后对一体化设计与传统分离设计进行了仿真对比。仿真结果表明:考虑位标器稳定跟踪回路与导弹姿态回路耦合的一体化控制器,不仅能够保证弹体姿态控制系统快速响应,还可以提高位标器的稳定跟踪性能,并降低位标器跟踪不上高速目标的可能性。
Due to the existence of parasitic loops, the stubborn coupling of the stabilizer and the projectile attitude control loop has a serious coupling, which affects the stability and tracking of the marker. Aiming at the stability and tracking problem of the semi-strapdown seeker stabilized platform, an integrated method of stabilizing tracking control and projectile attitude control is proposed. The control law is designed based on the backstepping control principle. The stability and dynamic performance of the system can be guaranteed by choosing the feedback gain rationally. Finally, the integrated design and the traditional separation design were simulated and compared. The simulation results show that considering the integral controller that the stabilizer tracker and missile attitude loop are coupled can not only ensure the rapid response of the projectile attitude control system, but also improve the stable tracking performance of the scaler and reduce the tracking of the scaler Not on the possibility of high-speed targets.
