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.
