Run-time assurance via real-time generation of trajectory and transverse dynamics regulation law
Abstract
In safety or mission-critical environments run-time assurance is about performing actions with full consciousness of opt-out options and the willingness to exercise such options when they are about to run-out. Autonomy in aerospace systems is one of the most delicate challenges in control theory due to the blatant catastrophic and tragic outcomes of control failures. This talk proposes a new framework for run-time assurance and closed-loop trajectory generation for nonlinear dynamical systems, which enjoys intelligent interaction with complex environments. This framework exploits the transverse dynamics to compute closed-loop control laws for optimal trajectories in complex obstacle environments in real-time. Finally, we will provide a three-state example in a complex obstacle environment for demonstration in which we will use the GuSTO algorithm for the generation of nominal control trajectories.
