- 요약Robots and autonomous vehicles must be able to operate safely and efficiently in the presence of environmental uncertainty, motivating the development of sophisticated motion planning algorithms for handling complex stochastic dynamics. However, the application of existing approaches is limited due to restrictions imposed on the structure of the dynam-ics and conservatism resulting from simplistic characterization of uncertainties. This thesis develops theoretical and experimental results motivated by two challenging robotic appli-cations within the domain of autonomous vehicles: off-road racing and interactive driving. For the first application, autonomous racing, we develop a stochastic model predictive con-trol (SMPC) algorithm for linear time-varying systems subject to unbounded disturbances which efficiently optimizes over the space of affine feedback policies using convex pro-gramming. We show that the proposed SMPC approach provides bounded convergence to a reference trajectory and guarantees polytopic chance constraint satisfaction with at least a specified probability during operation. We verify our approach using numerical and experimental demonstrations on a 1:5-scale autonomous rally racing platform as well as with a full-scale autonomous vehicle, and we demonstrate improved safety and reduced lap-times over a state-of-the-art method. For the second application, we consider interac-tive highway driving and develop a dual SMPC algorithm which employs active learning of unknown parameters of a general nonlinear system using Bayesian estimation. We show that the proposed approach induces probing behaviors to reduce parameter uncertainty, and we develop a novel sampling-based solver utilizing recent results for generative diffusion models to efficiently solve the dual control problem in real time. We validate the proposed dual SMPC approach by utilizing high-fidelity simulations and hardware experiments of an autonomous merge scenario in a congested traffic environment and demonstrate a superior merge success rate over state-of-the-art passive learning approaches.
