Networked Embedded Control Systems: from Modelling to Implementation

Networked Embedded Control Systems: from Modelling to Implementation

Discrete abstractions of continuous and hybrid systems have been the topic of intensive study in the last twenty years from both the control systems and the computer science communities, see e.g. [10]. While physical world processes are often described by differential equations, digital controllers and software and hardware at the implementation layer are usually modeled through discrete/symbol...

Multi-Agent Reconfigurable Embedded Systems: From Modelling to Implementation

The chapter deals with reconfigurable embedded control systems following component-based technologies and/or Architecture Description Languages used today in industry. The author defines Control Components as software units to support control tasks of the system which is assumed to be a network of components with precedence constraints. The author defines an agent-based architecture to handle a...

Hybrid Control of Networked Embedded Systems

Hybrid systems that involve the interaction of continuous and discrete dynamics have been an active area of research for a number of years. In this paper, we start by briefly surveying the main theoretical control problems that have been treated in the hybrid systems setting and classify them into stabilization, optimal control and language specification problems. We then provide an overview of...

Implementation Considerations For Wireless Networked Control Systems

We show that delay impulsive systems are a natural framework to model wired and wireless NCSs with variable sampling intervals and delays as well as packet dropouts. Then, we employ discontinuous Lyapunov functionals to characterize admissible sampling intervals and delays such that exponential stability of NCS is guaranteed. These results allow us to determine requirements needed to establish ...
