Abstract | Active optical primary mirror segmented technology is one of the most critical core technologies for ground-based large optical infrared telescopes. The co phase segment of mirror surfaces is the fundamental guarantee for giving full play to the optical performance of large primary mirrors. To achieve this goal, the performance of the position actuators presents a huge challenge. Considering the two key indicators of control accuracy and power consumption, we developed a new compound position actuator, which consists of a fine-tuning mechanism and an active offloading mechanism. For this new type of actuator, we have developed a high-performance control system based on the active disturbance rejection control algorithm. The experimental results show that the position actuator system we developed can achieve high-precision position tracking and position control,can meet the index requirements. |
