“Technology News Broadcast: A major breakthrough has been made in the field of space astronomical telescopes. Experts have proposed an adaptive precision image stabilization closed-loop control method based on active optics technology to address the issue of low-frequency visual axis disturbance compensation. This method utilizes a fine star guide as a high-precision visual axis disturbance detector, combined with a four point supported piezoelectric driven large aperture fast swing mirror mechanism for disturbance compensation. Through precise image stabilization closed-loop control, this method can accurately calculate the required swing angle to compensate for visual axis disturbances and convert it into the expansion and contraction of piezoelectric ceramic actuators at each support point. Meanwhile, a piezoelectric dynamic hysteresis feedforward compensation method based on the generalized Bouc Wen inverse model is adopted to achieve high-precision positioning control. In addition, this method also utilizes a single neuron with self-learning and adaptive capabilities to optimize the parameters of the PID controller, ensuring optimal control performance. The experiment shows that this method can effectively compensate for the visual axis deviation of space astronomical telescopes, and suppress the integrated values of the power spectral density of the centroid position deviation of the X and Y direction star points in the 0-6 Hz frequency band of the fine star guide by 98.54% and 98.62%, respectively. This achievement provides strong support for the precise observation of space astronomical telescopes and marks another important advancement in space optical control technology.”
