Control/Architecture Codesign for Cyber-Physical Systems

Abstract

Control/architecture codesign has recently emerged as one popular research focus in the context of cyber-physical systems. Many of the cyber-physical systems pertaining to industrial applications are embedded control systems. With the increasing size and complexity of such systems, the resource awareness in the system design is becoming an important issue. Control/architecture codesign methods integrate the design of controllers and the design of embedded platforms to exploit the characteristics on both sides. This reduces the design conservativeness of the separate design paradigm while guaranteeing the correctness of the system and thus helps to achieve more efficient design. In this chapter of the handbook, we provide an overview on the control/architecture codesign in terms of resource awareness and show three illustrative examples of state-of-the-art approaches, targeting respectively at communication-aware, memory-aware, and computation-aware design.

Semantics-Preserving Cosynthesis of Cyber-Physical Systems

“…Since there might be multiple controllers that satisfy given stability and performance speciications (safety properties), a better approach is to determine the controller and platform coniguration parameters together. In other words, by cosynthesizing the controller and platform coniguration parameters-i.e., as a part of a common optimization framework-we can ensure that the two designs are compatible (or model-level semantics are preserved) and there is a larger set of parameters that may be explored [4].…”
