Optimal Control of PC-PLC Virus-Mutation and Multi-Delay Propagation Model in Distribution Network CPS

The intelligent manufacturing of power systems has led to many challenges. cyber-physical system (CPS) was introduced solve the problem insufficient integration equipment and systems. It brings advantages, but also risks. In distribution network CPS, malicious attacks on PC-PLC communication can cause significant incidents affect safety. paper discusses two challenges, possible mutated virus multi-delay in coupled network. We present for first time a virus-mutation propagation model. Then, effectively control minimize cost, proposes five measures, introduces their combinations, solves optimal with Pontryagin maximum theorem. Finally, simulations verify strategies all combinations. By comparing effects control, minimum average strategy been proven be effective.
