Abstract

This paper presents a scheduling method for network-based control systems with three types of data (periodic data, sporadic data, and messages). As a basic parameter for the scheduling method for network-based control systems, a maximum allowable delay bound is used,which guarantees stability of network-based control systems and is derived from characteristics of the given plant using the presented theorems. The presented scheduling method for network-based control systems can adjust the sampling period as small as possible, allocate the bandwidth of the network for three types of data, and exchange the transmission orders of data for sensors and actuators. In addition, the presented scheduling method guarantees real-time transmission of sporadic and periodic data, and minimum utilization for nonreal-time messages. The proposed method is shown to be useful by examples
