Towards a Verified Artificial Pancreas: Challenges and Solutions for Runtime Verification

  • Conference paper
  • First Online:
Runtime Verification

Part of the book series: Lecture Notes in Computer Science ((LNPSE,volume 9333))

Abstract

In this paper, we briefly examine the recent developments in artificial pancreas controllers, that automate the delivery of insulin to patients with type-1 diabetes. We argue the need for offline and online runtime verification for these devices, and discuss challenges that make verification hard. Next, we examine a promising simulation-based falsification approach based on robustness semantics of temporal logics. These ideas are implemented in the tool S-Taliro that automatically searches for violations of metric temporal logic (MTL) requirements for Simulink(tm)/Stateflow(tm) models. We illustrate the use of S-Taliro for finding interesting property violations in a PID-based hybrid closed loop control system.
