The American Control Conference (ACC) is an annual 3-day meeting that brings together an international community of researchers and practitioners in all areas related to the engineering and science of control systems. It features presentations and discussions on the latest scientific developments as well as application successes and lessons learned. Participants convene to discuss the latest advances in the discipline, to shape its future directions, to provide training and educational opportunities for attendees, and to develop and maintain scientific and professional networks. The ACC program features plenary and semi-plenary lectures, contributed and invited papers, and tutorial and special sessions. Several pre-conference workshops are held. Annual awards recognize and honor individuals who have made significant contributions to control theory and practice. The conference typically attracts about 1300 participants and features about 1000 refereed papers. It is internationally recognized with about 40% participation from outside the United States. The 2019 ACC technical program will comprise presentations in regular and invited sessions, tutorial sessions, and special sessions along with workshops and exhibits. Submissions are encouraged in all areas of the theory and practice of automatic control.
