Adaptive navigation control of a bionic robotic fish in complex Karman vortex street flow fields using an LSTM-DDPG hybrid strategy
Changhui Zheng, Peigang Jiao, Honghao Xu, Yiheng Zhang, Jiaxin Shi
Bionic robotic fish suffer from poor navigation robustness, high energy consumption, and control lag in unsteady Karman vortex street flow fields. This study proposes a hybrid adaptive navigation strategy combining long short-term memory (LSTM) and deep deterministic policy gradi…
