Aim & Scope The IEEE Control Systems Letters (L-CSS) publishes peer-reviewed brief articles that provide a rapid and concise account of innovative ideas regarding the theory, design, and applications of all aspects of control engineering. General Information The L-CSS aims at ensuring rapid dissemination of the most recent results in the broad field of Systems and Control by providing its readers with the state of the art of research in the area. Submitted manuscripts must be typewritten in English. We require a double-column version at the time of submission. The maximum number of allotted pages is 6. Papers of length exceeding 6 pages, in 2-column, single-spaced format (including figures), will not be considered. The L-CSS is published quarterly and is available on-line through IEEE Xplore. It is sponsored by the IEEE Control Systems Society and technical co-sponsors include: the IEEE Circuits and Systems Society, the IEEE Systems, Man and Cybernetics Society and the IEEE Signal Processing Society. The IEEE Control Systems Letters and the IEEE Conference on Decision and Control and the AACC American Control Conference While submission to the L-CSS is open throughout the year, in some periods of the year, the Letters offers the opportunity for authors to not only publish a paper in the journal but also to present the same paper either at the flagship conference of the IEEE Control Systems Society: the IEEE Conference on Decision and Control (CDC), or at the annual conference of the American Automatic Control Council (AACC): the American Control Conference (ACC). This year for the first time the joint submission to IEEE Control Systems Letters and ACC 2021 is possible starting on July 1, 2020. Manuscripts submitted to the L-CSS with the CDC/ACC option will undergo a regular review as papers submitted to the Letters (so they should be submitted only to the L-CSS and not to the CDC/ACC). At the end of the first round of review, the reviews and the Associate Editor's report will be forwarded to the CDC/ACC Program Committee, which will use them to decide on the inclusion of these manuscripts in the program of the Conference. After the first round of review the decisions about the acceptance or rejection of the manuscript for the L-CSS and for the CDC/ACC will be independent of each other. Special Notice for Authors: Authors of articles reporting on research involving human subjects or animals shall confirm upon submission of an article to the Editor* whether or not an approval was obtained from a relevant Review Board. If such approval was obtained, the original source and reference shall be provided to the Editor* at the time of submission and shall appear in the article.
