Morphing UAVs can autonomously transform in response to changes in flight environments and tasks, always maintaining an optimal aerodynamic profile. The falcon-inspired morphing UAV folds\/twists its wings\/tail simultaneously to accomplish diving\/pull-out flight during the predation process. In the diving\/pull-out flight, falcon-inspired morphing UAVs are able to balance maneuverability and stability, which is hard to realize by current control methods. This paper proposes a deep reinforcement learning (DRL)-based diving\/pull-out cooperative control strategy. Considering the continuity of the state space and the action space of morphing UAVs, the deep deterministic policy gradient (DDPG) algorithm based on the actor-critic (AC) network is adopted and refined. With the aim of ensuring the smoothness of the flight action, the proposed DRL-based strategy is tasked with controlling multiple data frames of airspeed, altitude and pitch angle to desired reference values. Numerical experiments have been conducted on fixed-speed ascent\/descent flight and diving\/pull-out maneuvers flight missions. The results demonstrate the superiority of the proposed DRL-based control strategy compared with a classical proportional-integral-derivative (PID) control strategy. Furthermore, the proposed DRL controller is shown to generalize well to the random white noises which are added to gyroscope measurements and wind disturbance in flight. <\/jats:p>","DOI":"10.1142\/s2301385023410066","type":"journal-article","created":{"date-parts":[[2022,6,4]],"date-time":"2022-06-04T16:03:07Z","timestamp":1654358587000},"page":"191-202","source":"Crossref","is-referenced-by-count":7,"title":["Deep Reinforcement Learning-Based Diving\/Pull-out Control for Bioinspired Morphing UAVs"],"prefix":"10.1142","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1335-8955","authenticated-orcid":false,"given":"Bobo","family":"Ye","sequence":"first","affiliation":[{"name":"School of Mechatronical Engineering, Beijing Institute of Technology, No. 5 Yard, Zhong Guan Cun South Street, Haidian District, Beijing 100081, P.\u00a0R.\u00a0China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechatronical Engineering, Beijing Institute of Technology, No. 5 Yard, Zhong Guan Cun South Street, Haidian District, Beijing 100081, P.\u00a0R.\u00a0China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechatronical Engineering, Beijing Institute of Technology, No. 5 Yard, Zhong Guan Cun South Street, Haidian District, Beijing 100081, P.\u00a0R.\u00a0China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechatronical Engineering, Beijing Institute of Technology, No. 5 Yard, Zhong Guan Cun South Street, Haidian District, Beijing 100081, P.\u00a0R.\u00a0China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jichu","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechatronical Engineering, Beijing Institute of Technology, No. 5 Yard, Zhong Guan Cun South Street, Haidian District, Beijing 100081, P.\u00a0R.\u00a0China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yachao","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Mechatronical Engineering, Beijing Institute of Technology, No. 5 Yard, Zhong Guan Cun South Street, Haidian District, Beijing 100081, P.\u00a0R.\u00a0China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2022,7,29]]},"reference":[{"key":"S2301385023410066BIB001","doi-asserted-by":"publisher","DOI":"10.1177\/1045389X11414084"},{"key":"S2301385023410066BIB002","doi-asserted-by":"publisher","DOI":"10.1142\/S2301385022300013"},{"key":"S2301385023410066BIB003","doi-asserted-by":"publisher","DOI":"10.1016\/j.ast.2015.11.039"},{"key":"S2301385023410066BIB004","doi-asserted-by":"publisher","DOI":"10.1038\/nature05733"},{"key":"S2301385023410066BIB005","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.aay1246"},{"key":"S2301385023410066BIB006","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.abc2897"},{"key":"S2301385023410066BIB007","doi-asserted-by":"publisher","DOI":"10.1142\/S230138501750008X"},{"key":"S2301385023410066BIB008","doi-asserted-by":"publisher","DOI":"10.1142\/S2301385014300017"},{"key":"S2301385023410066BIB009","doi-asserted-by":"publisher","DOI":"10.2514\/2.2654"},{"key":"S2301385023410066BIB010","doi-asserted-by":"publisher","DOI":"10.2514\/1.46480"},{"key":"S2301385023410066BIB011","doi-asserted-by":"publisher","DOI":"10.1016\/j.ast.2016.03.009"},{"key":"S2301385023410066BIB012","doi-asserted-by":"publisher","DOI":"10.1098\/rsfs.2016.0085"},{"key":"S2301385023410066BIB013","doi-asserted-by":"publisher","DOI":"10.1007\/s12206-015-1226-3"},{"key":"S2301385023410066BIB014","doi-asserted-by":"publisher","DOI":"10.1098\/rsfs.2016.0092"},{"key":"S2301385023410066BIB015","doi-asserted-by":"publisher","DOI":"10.1088\/1748-3182\/8\/1\/016001"},{"key":"S2301385023410066BIB016","doi-asserted-by":"publisher","DOI":"10.1117\/12.914646"},{"key":"S2301385023410066BIB017","doi-asserted-by":"publisher","DOI":"10.1016\/j.ast.2019.05.063"},{"key":"S2301385023410066BIB018","doi-asserted-by":"publisher","DOI":"10.1109\/ICRA.2016.7487175"},{"key":"S2301385023410066BIB019","doi-asserted-by":"publisher","DOI":"10.1016\/j.egyr.2021.12.012"},{"key":"S2301385023410066BIB020","doi-asserted-by":"publisher","DOI":"10.12700\/APH.19.2.2022.2.9"},{"key":"S2301385023410066BIB021","doi-asserted-by":"publisher","DOI":"10.1007\/978-981-15-4095-0"},{"key":"S2301385023410066BIB022","volume-title":"Deep Learning","author":"Goodfellow I.","year":"2016"},{"key":"S2301385023410066BIB023","volume-title":"Reinforcement Learning: An Introduction","author":"Sutton R.
