What is it about?
The requirements for thermal control have increased with increasing resolution of space telescopes. Although some space telescopes can achieve temperature control accuracy of one thousandth of a degree Celsius under traditional control strategies, higher accuracy is still required. We proposed an intelligent autonomous thermal control strategy based on Actor-Critic reinforcement learning (RL) for proportional-integral-derivative (PID) parameter adaptive self-tuning, called RL PID. Both theoretical and experimental results show that RL PID has better reliability, more robustness, and a faster response than traditional control strategy.

Why is it important?
This is the first time the reinforcement learning algorithm is applied in the field of space telescope thermal control, and the effect is very good, for the future and the further research has the very good reference value
