Robot.

Kinematic and force analyses are performed to formulate the dynamics of a single-arm manipulator and the object using joint torque feedback technology and the Newton\u2013Euler formulation. To address uncertainties associated with the grasped object, a gradient model-based adaptive algorithm is developed for online estimation of the grasp matrix relating the object to the DRM. By employing an adaptive observer to identify unknown dynamic terms, an enhanced optimal performance index is constructed that incorporates both object tracking performance and internal force effects within the manipulator. The performance index function is approximated by only a critic neural network, and the optimal control policy is obtained by policy iteration. Lyapunov stability analysis demonstrates that internal force error, position tracking error, and critic network weight approximation error are all uniformly ultimately bounded. Experimental results confirm the effectiveness of the developed coordinated control approach.<\/jats:p>","DOI":"10.3389\/frobt.2026.1923646","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T05:23:33Z","timestamp":1788413013000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Adaptive dynamic programming for coordinated control of a dual-arm reconfigurable manipulator with unknown object constraints"],"prefix":"10.3389","volume":"13","author":[{"given":"Zebin","family":"Ji","sequence":"first","affiliation":[{"name":"Department of Control Science and Engineering, Changchun University of Technology","place":["Changchun, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Qin","sequence":"additional","affiliation":[{"name":"Aviation University of Air Force","place":["Changchun, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Control Science and Engineering, Changchun University of Technology","place":["Changchun, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hucheng","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Control Science and Engineering, Changchun University of Technology","place":["Changchun, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Control Science and Engineering, Changchun University of Technology","place":["Changchun, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,3]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"4691","DOI":"10.1109\/tcyb.2023.3277558","article-title":"Cooperative game-based approximate optimal control of modular robot manipulators for human\u2013robot collaboration","volume":"53","author":"An","year":"2023","journal-title":"IEEE Trans.
