报告摘要：

Modern control systems usually employ digital technology for controllerimplementation, i.e. sampled-data control. A classical approach to sampled-data control is based on discretization, which looses an information on theinter-sampling behavior and performance (Kalman and Bertram, 1959). To avoid the latter problem, a time-delay approach to sampled-data control was introduced in (Mikheev, Sobolev and Fridman, 1988), where the system was modeled as a continuous-time system with the delayed control input.

The time-delay approach to robust sampled-data control was started in (Fridman, Seuret and Richard, 2004) and it became popular in networked control systems (NCSs). These are systems, where the plant and the controller exchange data via communication network. Compared to traditional feedback control systems, where the components are usually connectedvia point-to-point cables, the introduction of communication network mediabrings great advantages, such as low cost, reduced weight, simple installation/maintenance and long distance control.

In the present talk three main approaches to sampled-data and network-based control will be discussed. A recent extension of the time-delay approach to networked-control systems will be demonstrated, where variable sampling intervals, communication delays and protocol scheduling are takeninto account. Also event-triggered control will be mentioned.
