A Cyber Physical System/Communication Framework for Resilient Real-time Control and Secure Operation of Ship
Abstract
The operation of naval ship power system necessities the integration of highly complex andinterdisciplinary systems and technologie"s. These systems range from physical systems, such as the powersystem~s physical components, i.e., generation, distribution, energy"" storage and power electronicsconverters to cyber components such as communication networks, embedded systems firmware andcomputin"g platforms. The goal of the integration between these technologies is to improve the reliabilityand real time performance of the s"hip loads and systems by improving the sensing and control networks,and provide necessary intelligence for decision making through" computing platforms and softwarecomponents. This complex integration and inter-dependability between the cyber and the physicalco"mponents, in these systems, can be utilized to solve many of the issues involved in real-time operationand control. The integration"" may however, introduce new vulnerabilities to the ship power systems. Therisk of vulnerability escalates when the level of integra"tion between the physical and cyber componentsincreases. Failures in communication or cyber components during normal operation or battle conditions canlead to cascaded failures and severe damage to the physical components. The design and optimization ofsuch complex systems require understanding the nature of the interaction and coordination between thecyber and physical components in order to obtain the best performance while minimizing vulnerability risk.The ship~s survivability and ability to maintain operation and" provide services in case of multiple faults, ineither the cyber or the physical components, greatly depends on the control system" architecture. The controlsystem should autonomously interact with different types of faults and reconfigure the system architectureto ensure proper operation under challenging conditions. The distributed multi-agent control providescapability to decentralize the ship~s power system control and avoids central decision-making issues. Theseintelligent agents will exchange the information and" the measurements during normal operational modes tooptimize the power system. During faults or loss of communications, they will w""ork autonomously tomaintain proper operation in the local area and provide fault isolation, reconfiguration and a self-healingmech""anisms. In order to study the complete system behavior, a cyber-physical system co-simulationframework for ship power systems, whic""h address both physical and cyber components, is required. Thecurrently available simulation, emulation and test beds focus only on"" either physical or the cyber parts ofthis important problem.This proposal aims to develop cyber-physical coordination, co-design"" techniques and methodologiesfor the ship power system to minimize the risk of the vulnerability, cost, and optimize system operati"ons.The proposal will also develop an optimal distributed multi agent network architecture for real timeoperation and control. The" developed process will identify the number of agent levels, agent types andconnection topology required for optimum control. Furth""ermore, the proposal aims to develop a frameworkfor cyber physical system co-simulation with the power system. The proposed effort" will integrate thisframework with the existing FIU ship power system test bed to perform verifications of developed realtimecontrols and hardware-in-the-loop (HIL) simulation environment. The proposed effort will alsoinvestigate different security aspects of t"he hybrid cyber physical system to develop detection and selfhealingmechanisms that comply with the ship power system operation, se""curity and authenticationrequirements. Finally, we will verify the practical implementation and testing of the developed designopt"imization techniques and multi-agent control on the FIU test bed.
