| Popis: | 92 In modern industrial control system, the applications about the hybrid system composing of a discrete event system and a continuous state system are developing to an important issue. Specially, in the large-scale industrial control system the system’s complexity can be reduced by using the supervisory control technology of a hybrid system. As a result of an energy management system is a complex control system including many components with different properties. The control actions include continuous state signals and discrete events such start the system, stop the system etc. For efficient monitoring and control the energy system such that the objectives of energy conservation and facility management are achieved, the supervisory control technology of hybrid systems is a feasible method. In this research, first the decentralized control HVAC system which is the most important and complex system in the energy management system is modeled as a hybrid dynamical system. The model includes four event operating modes. Then the switching stability between different modes is analyzed by using multiple Lyapunov function, and the system’s performance specifications are determined. The simplified discrete event plant model of the HVAC system is provided for supervisory control, and the supervisory control architecture is designed. A agent-based energy management in communication network is discussed in this dissertation. The java program based Mobile Agent is the tool for information exchange. A supervisory control architecture in the remote control system will also be provided, then a simple communication and control experiment is proceeding to verify the structure’s capability. |
