利用最佳控制和估值理论,对战术导弹整体式捷联制导和控制系统进行了设计。所用敏感元件为捷联式速率陀螺、加速度计及捷联式寻的头。对助推段倾斜转弯导弹拦截机动目标的战例,给出了它的误差灵敏度和性能特点。在同高度侧向攻击(侧偏运动)时,若传感器性能完好,脱靶距离可小于4英尺。传感器的主要误差源是寻的头量化和陀螺刻度系数误差。此外,在命中目标前,寻的头失控(即“盲区”)及采样间隔对末段性能和末端脱靶距离也有重要影响。
The tactical missile integrated strapdown guidance and control system was designed using the best control and valuation theory. Sensitive components used for the strapdown rate gyroscope, accelerometer and strapdown search header. The error sensitivity and performance characteristics of the assault segment tilt turn missile intercepting the maneuver target are given. In the same height lateral attack (lateral movement), if the sensor performance intact, off-target distance of less than 4 feet. The main source of error for the sensor is the head quantization and the gyro calibration coefficient error. In addition, prior to hitting a target, missing headers (ie, “dead zones”) and sampling intervals also have a significant effect on the final performance and end-of-range distances.
