Abstract :
This paper presents a scheduling method for network-based control systems with three kinds 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 Lyapunov theorem. The presented scheduling method for network-based control systems can adjust the sampling period as small as possible and allocate bandwidth of network for three kinds of data. In addition to those, the presented method guarantees real-time transmission of sporadic and periodic data, and minimum transmission for messages. The proposed method is shown to be useful by an example
