A High-Precision and Fast-Pointing Mechanism Control Method for Space Remote Sensing Camera
High-precision and fast-response pointing mechanisms are critical components in space remote sensing cameras. In order to obtain high quality remote sensing images, the control precision of the scanning mechanism is required to be arcsecond-level. Addressing the current limitations in response speed and control accuracy of fast-pointing mechanisms, this paper proposes a control algorithm based on feedforward and secondary-loop feedback. Simulation and experimental results demonstrate that the proposed algorithm enhances response speed and control accuracy while maintaining strong robustness
