为了进一步提升机动平台的遥感侦查能力,在惯性稳定平台的基础上,结合光电探测信息通路中的快速反射镜,构成惯性/光机复合指向系统,借助快返镜的快速运动补偿惯性稳定回路的伺服误差,可有效提高探测光轴的稳定精度与指向跟踪的机动性能。将惯性稳定回路与快反镜控制回路转化为平行的双入单出系统,针对两者作用频带与作动范围的差异,提出一种惯性/光机复合指向控制方法,解决系统中惯性稳定机架指向与快反镜指向叠加的稳定性匹配和频带分解问题,从而提升光轴的稳定精度和机动性能。仿真结果表明:加入了快反镜的惯性稳定平台的误差有显著减小,其跟踪误差量从0.018°减小到0.005°以内,验证了控制器设计的有效性。
In order to further improve the capability of remote sensing detection of the mobile platform, based on the inertial stable platform, combined with the rapid reflection mirror in the photodetection information path, the inertial / optical composite pointing system is constructed, and the fast motion compensation inertial stabilized loop Servo error, which can effectively improve the stability of the probe optical axis and the tracking performance. The inertia stabilization circuit and the fast reflector control loop are transformed into parallel double-in-single-out system. In view of the difference between the two operation frequency bands and the operation range, an inertial / optomechanical composite pointing control method is proposed to solve the problem that the inertial stabilizer Frame pointing and superfocus mirror superimposed on the stability of the match and band decomposition problems, thereby enhancing the optical axis stability and maneuverability. The simulation results show that the error of the inertial stabilized platform with the fast reflector is significantly reduced, and the error of the tracking error is reduced from 0.018 ° to 0.005 °, which verifies the effectiveness of the controller design.
