Center node: "time optimal path tracking online scaling with guarantees"
  Abstract: Given a geometric path, the Time-Optimal Path Tracking problem consists in finding the control strategy to traverse the path time-optimally while regulating tracking errors caused by model inaccuracies and online perturbations. Online Scaling (OS) is a simple yet effective approach to this problem. The overall OS controller is composed of two components: (i) a path controller, which modulates the parameterization of the desired path in an online manner, yielding a reference trajectory; and (ii) a torque controller, which takes the reference trajectory and outputs torque commands for tracking. However, OS has one major drawback: the path controller might not find any feasible reference trajectory that can be tracked by the torque controller because of torque constraints. In turn, this results in degraded tracking performances. Here, we propose a new controller, termed Online Scaling with Guarantees (OSG), which is guaranteed to find a feasible reference trajectory by accounting for all possible future perturbations. Our approach is based on Robust Reachability Analysis. Simulations show that the OSG controller outperforms existing methods.
