A fuzzy rule-based and energy-efficient method for estimating the free size of parking places in smart cities is proposed. In particular, the estimation is the output value of a fuzzy inference system (FIS) which was implemented on each wireless sensor mote (WSM) of a wireless sensor network (WSN) placed in the ground below the parking places and it was observed that it requires 8.9 Kbytes and 5 Kbytes of flash program memory and RAM respectively. Moreover, the fuzzy rules were formulated by using real numerical data obtained from the WSN. Next, the well known network simulator 2 (NS-2) was used for acquiring simulation results concerning the energy consumption of the battery of the WSMs. In order to model the error of the output value of the FIS and the energy consumption of the battery, a data fitting problem was solved and the cubic polynomial was fitted to the real and simulation data. As a result, a real-valued cost function was formed which was minimized to get the optimal values for the distance between the WSMs and the sampling period based on which the output of the FIS should be re-computed.

The manual partitioning of virtual machines with real-time requirements onto a multi-core platform is expensive, does not guarantee to find an optimal solution, and does not scale with regard to the upcoming higher number of both virtual machines and processor cores. This work proposes an algorithmic solution. As a prerequisite, the partitioning problem is defined in a formal manner by the abstraction of computation time demand of virtual machines and computation time supply of a shared processor core. In particular, we propose a branch-and-bound partitioning algorithm that systematically generates and evaluates candidate solutions. Combined with a computation time server based scheduling of the virtual machines that are mapped to the same core, it is guaranteed that the computation time demand of all virtual machines is satisfied. The utilization is optimized by transforming to harmonic server periods. The partitioning either minimizes the required number of cores or maximizes the distribution of critical virtual machines. The different outcomes of the algorithm according to these two goals are illustrated exemplarily and evaluated with random workloads.

This paper introduces an H∞ current controller that allows the shaping of power converters' input admittance in frequency domain, allowing to define not only its magnitude but also its phase. In addition to admittance shaping, some current tracking specification are also introduced to the algorithm demonstrating that both admittance shaping and tracking performance are possible, but not at the same frequencies. The correct performance (both in time and frequency domain) of the proposed method is demonstrated in an L-filter grid-connected single-phase VSC.

In this paper we analyse the conditions that produce oscillations in event based PID controllers. A Symmetric Send-On-Delta scheme (SSOD) is assumed, and the describing function is the tool used to address the problem. Once the conditions for oscillations are established, a new robustness to oscillations performance measure is introduced. Then a very simple and intuitive rule of thumb is given about how to tune PID controllers to avoid the limit cycles. The rule presented here entails with the classical concept of phase margin, providing the key to design SSOD based PID by using continuous PID tuning methods. The proposed ideas are tested in simulations with a batch of models widely used in PID design methods testing.

Distributed systems rely in communication networks, typically a bus, in order to exchange messages and fulfill their goals. However, message transmission is subject to interferences that ultimately can lead to message corruption. In systems where a high-reliability is sought, error recovery mechanisms can be deployed in order to give the required reliability level, and this can be done in the spatial or temporal domain. In the scope of the FTT paradigm, and applied to the FTT-CAN protocol, the authors have previously presented a time domain recovery method using message retransmissions controlled by a server. In this article we assess the impact of different scheduling policies for the server, presenting a qualitative evaluation of the alternatives, complemented by a simulation study, in order to verify their advantages and weak points.

The industrial machinery reliability represents a critical factor in order to assure the proper operation of the whole productive process. In regard with this, diagnosis schemes based on physical magnitudes acquisition, features calculation, features reduction and classification are being applied. However, in this paper, in order to enhance the condition monitoring capabilities, a forecasting approach is proposed, in which not only the current status of the system under monitoring in identified, diagnosis, but also the future condition is assessed, prognosis. The novelties of the proposed methodology are based on a distributed features forecasting approach by means of adaptive neuro-fuzzy inference system models. The proposed method is validated by means of an accelerated bearing degradation experimental platform.

Industrial communication systems, like the very popular real-time Ethernet networks, are ever more used to carry multimedia traffic, i.e. that generated by applications employing complex sensors such as, for example, video cameras. Ethernet networks, however, revealed to be quite inefficient in terms of energy saving since the power consumption of a link between any two devices does not decrease significantly during the (statistically long) idle periods, i.e. the intervals of time in which the link is not crossed by traffic. In this paper we present a novel traffic shaping technique that aims at saving energy when the multimedia industrial traffic has self similar characteristics. In particular, the proposed method combines the statistical properties of the traffic, with the opportunities offered by the recent amendment to the Ethernet standard, called Energy Efficient Ethernet (EEE), to design a strategy based on the analysis of current traffic levels and the prediction of the incoming data flow. Simulation results are presented to prove the effectiveness of the strategy which leads to considerable energy savings at the expense of only a limited bounded delay in frame delivery.

Upon its first release, the FDI standard (field device integration, IEC 62769) [1] will be the most widely accepted standard for field device integration in automation industry [6]. Although it is a very new standard, the underlying technology re-use protects investments in customer installed base on an even wider scale. Still, FDI-related work has mostly been focused on the support of field instruments and compact electrical devices. Toward a complete coverage of all automation devices with one integration technology, we have therefore investigated the potential of FDI to also support the particularities of modular electrical subsystems. Using ABB's low-voltage switchgear MNS iS as a case study, we have attempted to practically port the relevant parts of the existing tool chain to FDI technology. While other modular devices such as remote IOs typically come from the same vendor as the device management system (DMS) and therefore may be supported in a proprietary manner, we must be able to integrate electrical subsystems into an FDI system like any compact device: by loading standard-conforming description files. Given the approval state of the standard and the still ongoing development of common FDI software components, we find the results rather encouraging. From the gaps we found in both the standard and the currently available implementation, we have concluded a set of proposals for action. We are confident that with reasonable effort the value of FDI can be enhanced even further.

This paper presents and innovative technique-referred to as trend-weighted rule-based expert system (TWRBES) - grounded in the integration of two existing tools of the artificial intelligence field, expert systems (ES) and qualitative trend analysis (QTA). The main goal of this approach is to benefit of the main advantages associated with each of the techniques used, such as the ability to represent knowledge through rules and the ability to extract the behavior and the trends of a continuous signal. Such integration allows a direct purpose in industrial environment applications, especially in the intelligent automation field. This paper introduces this technique and preliminary results obtained from applying it to industrial process diagnosis.
