Control of Large-Scale Cyber-Physical Systems with Agents via a Representative Model

In this paper, a controller design methodology is discussed for a large-scale cyber-physical system (CPS) with agents having various characteristics. Especially, a representative model is introduced, which helps us to design controllers. Actually, the representative model is of much lower order than the scale of the large-scale CPS, and thus designing a controller for this model is much easier. In this paper, we derive a representative model such that a controller designed for this model stabilizes the original large-scale CPS with given control performance. The derived representative model is in the form of a nominal model with the average discrepancy.
