Equalized recovery: Weakening invariance for control and estimation: poster abstract
HSCC '19: Proceedings of the 22nd ACM International Conference on Hybrid Systems: Computation and ControlPages 276–277https://doi.org/10.1145/3302504.3313358When deployed into real environments, control systems need to be able to operate when their sensor data can become 'missing' (e.g., a vehicle's radar system may incorrectly detect a falling leaf as a vehicle on the road, or a distributed control system ...

Formal verification of neural network controlled autonomous systems
HSCC '19: Proceedings of the 22nd ACM International Conference on Hybrid Systems: Computation and ControlPages 147–156https://doi.org/10.1145/3302504.3311802In this paper, we consider the problem of formally verifying the safety of an autonomous robot equipped with a Neural Network (NN) controller that processes LiDAR images to produce control actions. Given a workspace that is characterized by a set of ...

Mixed-integer formulations for optimal control of piecewise-affine systems
HSCC '19: Proceedings of the 22nd ACM International Conference on Hybrid Systems: Computation and ControlPages 230–239https://doi.org/10.1145/3302504.3311801In this paper we study how to formulate the optimal control problem for a piecewise-affine dynamical system as a mixed-integer program. Problems of this form arise typically in hybrid Model Predictive Control (MPC), where at every time step an open-loop ...

On the decidability of reachability in linear time-invariant systems
HSCC '19: Proceedings of the 22nd ACM International Conference on Hybrid Systems: Computation and ControlPages 77–86https://doi.org/10.1145/3302504.3311796We consider the decidability of state-to-state reachability in linear time-invariant control systems over discrete time. We analyse this problem with respect to the allowable control sets, which in general are assumed to be defined by boolean ...
