The diving control problem is formulated as a disturbance attenuation problem, in view of achieving the desired performance by attenuating the internal as well as the external disturbances by ensuring internal stability and robustness. Two Hamilton\u2013Jacobi\u2013Isaacs inequalities have been formulated in the form of a Taylor series technique to determine solutions to the control algorithms. The solution of the first Hamilton\u2013Jacobi\u2013Isaacs inequality renders a state feedback control law whereas the second inequality is exploited to design a nonlinear observer for estimating the autonomous underwater vehicle states in order to realize an output feedback controller. These control algorithms are implemented firstly using the MATLAB\/Simulink environment and then, the experimental validation of the developed control algorithm has been performed in order to ensure the effectiveness of the control scheme.\n                  <\/jats:p>","DOI":"10.1177\/0142331217695671","type":"journal-article","created":{"date-parts":[[2017,3,22]],"date-time":"2017-03-22T18:44:59Z","timestamp":1490208299000},"page":"2024-2038","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":26,"title":["Nonlinear\n                    <i>\u210b<\/i>\n                    <sub>\u221e<\/sub>\n                    state and output feedback control schemes for an autonomous underwater vehicle in the dive plane"],"prefix":"10.1177","volume":"40","author":[{"given":"Subhasish","family":"Mahapatra","sequence":"first","affiliation":[{"name":"Centre for Industrial Electronics and Robotics, Department of Electrical Engineering, National Institute of Technology Rourkela, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bidyadhar","family":"Subudhi","sequence":"additional","affiliation":[{"name":"Centre for Industrial Electronics and Robotics, Department of Electrical Engineering, National Institute of Technology Rourkela, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,3,22]]},"reference":[{"key":"bibr1-0142331217695671","doi-asserted-by":"publisher","DOI":"10.1201\/b10734"},{"key":"bibr2-0142331217695671","doi-asserted-by":"publisher","DOI":"10.1007\/s11804-011-1077-y"},{"key":"bibr3-0142331217695671","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cta:20050357"},{"key":"bibr4-0142331217695671","doi-asserted-by":"publisher","DOI":"10.1080\/002071799220515"},{"key":"bibr5-0142331217695671","doi-asserted-by":"publisher","DOI":"10.1109\/9.29425"},{"key":"bibr6-0142331217695671","first-page":"386","volume-title":"Proceedings of 9th IEEE international conference on control and automation","author":"Ferreira HC","year":"2011"},{"key":"bibr7-0142331217695671","unstructured":"Fossen TI (1994) Guidance and Control of Ocean Vehicles.
