Spacecraft rendezvous, quadrotors in wind, and mobile robots in changing environments all require decisions under constraints, uncertainty, and shifting objectives. Model-based optimal control provides physics-grounded predictions and hard constraint satisfaction, while reinforcement learning adapts from experience but can violate constraints and lacks interpretability. This work develops a unified framework for constrained trajectory optimization that combines these paradigms, targeting real-time performance with safety guarantees. The methodology is grounded in interior-point iLQR\/DDP and introduces three main advancements. First, a multiple-shooting formulation integrated with interior-point methods enables robust convergence from dynamically infeasible initializations without sacrificing efficient Riccati structure. Second, chance-constrained DDP provides probabilistic safety margins using closed-loop covariance propagation, and GPU acceleration enables richer uncertainty evaluation to support hardware validation. Third, implicit KKT differentiation yields a differentiable constrained MPC layer that integrates with broader autonomy stacks and preserves hard constraints. Validation spans representative platforms, including spacecraft, aerial vehicles, and ground robots. Overall, the work enables learning-driven adaptation while maintaining real-time performance and hard constraint satisfaction.\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EDifferentiable Planning and Control for Autonomous Robotic Systems\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Differentiable Planning and Control for Autonomous Robotic Systems "}],"uid":"27707","created_gmt":"2026-01-22 17:42:25","changed_gmt":"2026-01-22 17:43:14","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-01-23T09:00:00-05:00","event_time_end":"2026-01-23T10:30:30-05:00","event_time_end_last":"2026-01-23T10:30:30-05:00","gmt_time_start":"2026-01-23 14:00:00","gmt_time_end":"2026-01-23 15:30:30","gmt_time_end_last":"2026-01-23 15:30:30","rrule":null,"timezone":"America\/New_York"},"location":"Online via Microsoft Teams","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
