Optimal Observation for Cyber-physical Systems A Fisher-information-

Cyber-physical systems (CPS) embody the interaction between a computing system and a physical process, being distinguished from traditional embedded systems by being designed as networks of interacting elements rather than as isolated devices. The wireles

Preface

Cyber-physical systems (CPSs) are emerging as an integrative research field aimed towards a new generation of engineered systems. From a dynamic systems and control point of view, CPS can be defined in the following way: “computational thinking and integration of computation around the physical dynamic systems form CPSs where sensing, decision, actuation, computation, networking, and physical processes are mixed.” CPS applications can be found in medical devices and systems, patient monitoring devices, automotive and air traffic control, advanced automotive systems, process control, environmental monitoring, avionics, instrumentation, oil refineries, water
