Reinforcement learning based robust control algorithms for coherent pulse stacking

Abstract

For the fast and robust control of the delay lines for coherent pulse stacking, we combined the stochastic parallel gradient descent with momentum (SPGDM) and the soft actor-critic (SAC) into a powerful algorithm, SAC-SPGDM. The simulation shows that the algorithm can find the optimal delay-line positions to ensure the 128 pulses are coherently stacked for 7-stage pulses stacking within 25 steps.
