New Method to Ameliorate the Large Telescope Speed Smoothness
After rising the smoothness problem of the telescope low speed condition, we develop a new servo controlling method for large optical telescope that combine PID with repetitive controller. Analysis shows that this controller has a strong ability to overcome the periodical disruption and a rapid reaction to any action. Working with the improved repetitive controller can achieve a high precision. Practically, we reach to the target successfully.
