Plug and Play Design in the Electric Vehicle Systems

Abstract

The plug and play concept focuses on the design of complex control systems with multiple functional building blocks. Each of the blocks fulfills certain specifications, is designed separately and might be delivered by different  vendors. Concerning vehicle systems complexity is handled in the integrated design framework built around a supervisory architecture. This paper investigates the possibilities of the plug and play design built in the supervisory integrated control. The supervisory control makes decisions about the necessary interventions, guarantees coordination between components and meets performance specifications. The well-defined interfaces provide that the decisions are propagated between the supervisor and the local components. Therefore the interfaces between components have crucial roles. The concept of the plug and play design is presented and several design methods based on the weighting strategy in the closed-loop interconnection structure are proposed.
