Abstract

A communication network for use in feedback control must satisfy strict requirements on the reliable and deterministic behavior. However, wireless sensor networks such as ZigBee may introduce randomly varying delays into the system, resulting in the performance degradation or even the instability. In this paper we propose a deterministic wireless network that can be used for feedback control. The proposed approach is based on a time-triggered mechanism implemented on top of the IEEE802.15.4 standard. The effectiveness of the proposed method is demonstrated through a set of experiments on feedback control of a DC motor.
