Over the last few years, systems have become a combination of multiple disciplines, such as mechanical, electrical, electronics and software engineering. A great number of methods have been introduced to face the increasing complexity of mechatronic systems but all show difficulties on integrating the various methodologies and competences of the single disciplines. For this reason, we are going to propose a brand-new design methodology and we have started here from the identification of some fundamental tools.

Interoperability is one of the most important features expected from distributed automation architectures. Achieving interoperability involves addressing issues related to synchronization of behavior, communication protocols, and data presentation formats. In this paper a case study on deployment of an automation application to a network of control devices with three different hardware/software platforms is presented to exploit benefits of the IEC 61499 architecture. Firstly, an overall control application with essentially distributed logic was created. This control application was then validated using closed-loop simulation and finally deployed to a network of control devices.

In this work, two alternative methodologies for modeling and predicting gas emissions of NO, NO2 and SO2 are presented. The first method involves hard modeling strategies with Parsimonious Multivariate Least Squares (PMLS) assuming simple polynomial functions as base model. The second is a soft modeling approach using Extreme Learning Machine (ELM). In this work we found that both methods have similar capabilities for data description, providing an in depth analysis of the system under study. Results also reveal further insights in predicting gas emissions and enlighten on which of the factors can be useful for prediction, and consequently for system characterization and emission abatement.

Virtualization is a promising solution to develop complex embedded systems with real-time requirements. This paper discusses the current state-of-the-art in virtualization technologies, with a particular focus on solutions for embedded real-time systems. Several such solutions have been developed over the past decade, and in this paper we give an overview of the more well known technologies and we provide a comparative assessment of key virtualization techniques available in these solutions. Gaps and lacking pieces are identified and further development and research is suggested.

We present a modified type-I level-up shifter with improved Process-Voltage-Temperature (PVT) robustness, propagation delay and energy consumption. Compared to a standard cross-coupled level-shifter, the circuit comprises a couple of long channel parallel P and N transistors to implement larger PMOS on-resistance maintaining unvaried upstream logic fan-out. Simulation results show significant robustness increase with respect to a standard topology maintaining low NMOS-to-PMOS sizing. Switching energy consumption is reduced from ~ 10pJ to 200fJ and propagation delay from ~ 240ns to 1ns. With Monte Carlo process variation simulations we have verified a reduction in output delay sensitivity from 209ns to 333ps while with transient noise simulation jitter is reduced from 3.5ns to 36ps. Operating ranges are wider in the proposed circuit, while sensitivity to temperature is comparable for high values. A prototype of this drain-degenerated logic-translator has been fabricated in a 130nm CMOS technology and evaluated with measurements.

Recent modular avionics architectures have been designed to share computation and communication resources. However, such an approach creates new challenges to master the temporal properties of avionics applications. In the context of IMA (Integrated Modular Avionics), it is crucial to investigate the performance gains that future integration platforms and software will propose. This paper brings to light the impact of spatial and temporal integration choices on the communication performance (e.g. message loss rate, latencies, ...). The conclusion of this investigation is that it is necessary to conduct a thorough modeling and simulation study of an IMA architecture integrating several applications during its early design stages.

In this paper we present a procedure for the marking estimation of a Time Petri net system in the presence of unobservable (silent) transitions. Starting from the State Class Graph presented by Berthomieu and Diaz, we introduce a new graph called Modified State Class Graph that gives a representation of the evolution of the timed system. Then, we present a procedure that, given a timed observation, i.e., a sequence of observable transitions with their firing time instants, and a time instant τ, allows one to determine in which markings the system can be at time τ by solving a certain number of linear programming problems.

Decentralized control approaches arise as promising solutions to cope with the high complexity of interconnected networks such as in the traffic domain. Leaving the control of traffic flow in the hands of distributed traffic nodes opens up the potential for a more efficient network utilization and a higher adaptability to changing traffic conditions. However, some control approaches based on decentralized information handling will introduce information delays which can result in suboptimal system performance and unintended effects such as oscillating traffic flows and traffic congestions. This paper compares the performance of a robust PI control approach without and with Smith predictor for an automated traffic control node with delayed traffic information. Results are validated with a realistic traffic simulation tool.

This work addresses the problem of controlling unknown and time varying plants for industrial applications. To deal with such problem several Self-Tuning Controllers with a Proportional Integral and Derivative (PID) structure have been chosen. The selected controllers are based on different methodologies, and some use implicit identification techniques (Single Neuron and Support Vector Machine) while the others use explicit identification (Dahlin, Pole placement, Deadbeat and Ziegler-Nichols) based in the Least Squares Method. The controllers were tested on a real DC motor with a varying load. The results have shown that all the tested methods were able to properly control an unknown plant with varying dynamics.

Handling of obsolete software and/or hardware components together with management of function updates in a complex embedded system with an expected life time of more than 30 years can be a very difficult to almost impossible task. This types of challenges can be found in a large number of companies in, for example, the power transmission industry, power plants, aviation etc. In this paper we present the basic steps in a proposed method for handling evolvability in such embedded systems with long expected life cycles. The key elements of the proposed method are the definition of function dependencies, release planning, and test requirements.
