First, the concept of safety is formalized for input-constrained dynamical systems. Safety properties appear as state constraints and system safety is defined with respect these constraints using the notion of forward invariance. Next, the research moves toward identifying a general theory of Run Time Assurance (RTA). RTA relates to a control system architecture where a performance-oriented element is augmented with a safety-driven element that filters the control signal in such a way that precludes harmful decisions. Importantly, the adoption of an RTA architecture allows for research on both performance and safety fronts to be pushed in parallel, and as such the results in this research are complementary to results in performance-based research. The latter part of the thesis consists of application-specific research for various problems on space systems, including autonomous rendezvous and docking subject to collision avoidance constraints, attitude control subject to line-of-sight constraints, and collision-inclusive planning for free-flying intravehicular robots.\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Optimization-based Approaches to Safety-Critical Control, with Applications to Space Systems "}],"uid":"27707","created_gmt":"2021-07-06 19:07:40","changed_gmt":"2021-07-06 19:07:40","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-07-21T14:00:00-04:00","event_time_end":"2021-07-21T16:00:00-04:00","event_time_end_last":"2021-07-21T16:00:00-04:00","gmt_time_start":"2021-07-21 18:00:00","gmt_time_end":"2021-07-21 20:00:00","gmt_time_end_last":"2021-07-21 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
