Future small unmanned aircraft systems will require careful codesign over both physical and cyber elements to maximize total system efficiency. Mission objectives and success of the system as a whole are becoming increasingly dependent on appropriate allocation of computational resources balanced against demands of the physical actuation systems. In this paper, a cooptimization scheme is described that considers tradeoffs between costs associated with the physical actuation effort required for control and the computational effort required to acquire and process incoming information. A small unmanned aircraft system surveillance mission, the visual inspection of a pipeline, is proposed to investigate specifics of cyber–physical cost terms and their tradeoffs. A multidisciplinary cost function minimizes energy and maximizes mission efficiency and effectiveness. Pareto fronts are examined over combinations of competing cyber and physical objectives, and they demonstrate that excluding either cyber or physical cost terms results in reduced performance for the holistic system over the course of the mission.
