摘    要： With the explosive growth in computing and networking technology, there has  been an increasing reliance on distributed computing and process operations based on computer networks. As an example, the power industry is moving towards active monitoring and control through wide-area measurement systems that are accessed over networks.

In a network distributed control system, the system elements such as actuators, sensors, and controllers are typically spatially isolated from one another, operating in an asynchronous manner, and communicating over a wide area via both wired and wireless links. Such distributed digital control systems present new challenges for control engineers and designers because of the interactions between control and communication components; network imposed constraints such as communication delays, packet dropout, and finite channel capacity must be considered in control analysis and synthesis.

In this talk, we will examine issues in networked control systems, discuss our recent results on state estimation, controller design, a data transmission strategy and related stability analysis, and finally, outline some future research in this area.
