中文摘要: 互联控制系统在实际应用中普遍存在。由于互联系统具有区域分布性质,随着网络通讯技术与控制理论的发展,互联系统信息传递的网络化成为必然趋势。互联系统的复杂性、网络通讯的不实时性及不可靠性等因素使传统的控制方式对网络化互联系统不再适用。本项目拟研究:1)剖析网络运行的内在规律、研究网络动态和互联系统的关联特性,建立统一的网络化互联系统的动态模型,改变由简单假设来刻画网络动态行为的研究方法;2)联立网络动态参数及系统采样、发送前后的数据,建立按系统所需,尽网络所能的数据传送机制,设计网络和被控系统协同控制的控制策略,协调优化网络服务质量和互联系统的控制性能;3)研究互联系统传感器/执行器等控制组件在增益缺失和链路故障等信息受限情景下的可靠性控制策略。分布式互联系统采用智能电网中广域多区发电控制系统,在实验室开发半物理仿真平台。项目的研究成果必将在实际工业应用中产生重要的理论和实践指导意义。

英文摘要: Interconnected system is widespread in practice. It is an inevitable trend to communicate the signals of the interconnected system over the network due to the wide-area location of the subsystems and the development of the communication technology. The control strategy of the networked interconnected system can not be used any more due to the feature of the network, such as the complication of the network, unreal-time, unreliability of the network,etc.. The further study will be developed from the following aspects: 1) To develope an integrated model of the networked interconnected system by researching the nature of the network dynamics and studying the correlated behaviors between the network and the interconnected system. The new model of the system is different from the conventional ones described by a certain assumption of the network. 2) To develop a hybrid-triggering scheme by combining the parameters of the network dynamics and the sampling/sending data. To adjust the parameters of the triggering and the coordinated control scheme to ensure the network is unblocked and the performance of the interconnected system is good. In the process of adjusting, the parameters of the network windows and the flow of the data is automatically adjusted as the performance need. 3) Based on the results of the item 1) and 2), the missing measurement of the sensor/actuator and the constrain of the information are considered to achieve a reliable control strategy. The platform of the semi-physical simulation will be built in the background of intelligent multi-area power generating systems. The results of the research will be contributed to the application of the practical industrial systems.
