The successful operation of Networked Control Systems (NCS) requires employing appropriate approaches for dealing with network induced time delays, i.e. time intervals elapsed from consecutive sampling and actuation operations. Effective approaches often require to impose periodic execution for the sampling and/or actuation operations, enforcing synchronized constant time delays. And considering that...
The Controller Area Network (CAN) provides the basis for many cost-effective distributed embedded systems. In this paper, we present a novel approach to networked control systems (NCS) analysis and design that provides increased control performance for a set of control loops that share a single CAN network. This is achieved by enabling the following functionality for each control loop: first, standard...
This paper presents a preliminary approach to networked control systems (NCS) that relies on an event-driven control method based on Lyapunov sampling. The goal is to study and develop approaches for NCS capable of offering controllers with low bandwidth demands. The paper starts by presenting the theoretical framework required for applying Lyapunov sampling to a set of closed-loop systems that share...
Wireless communication systems used in industrial environments must guarantee that the information is sent and received within precise time-bounds. However the nature of the radio channels and the medium access control (MAC) generates random communication delays. For networked control systems, these delays can cause severe performance problems. This paper presents an autonomous guided vehicle (AGV)...
