Control technology of airborne photoelectric tracking system

Abstract In order to achieve effective control of the airborne photoelectric tracking system and optimize the system control performance, accelerometers are introduced on the basis of the traditional gyroscope-based dual-loop control to optimize the performance of the control system. However, accelerometer signals are subject to errors due to both drift and noise in the lower frequency bands, which affects the effectiveness of the control system. In order to address this issue, an acceleration signal fusion method is proposed to obtain more accurate acceleration signals using velocity difference to fuse with accelerometer signals. The fused acceleration signals are used to implement acceleration feed-forward control to optimize control performance.
