As vehicles become more intelligent for safety and convenience of drivers, IVN(In-Vehicle Network) requires high speed of transmission and hardware redundancy for safety. FlexRay was developed to replace Controller Area Network (CAN) protocol in chassis networking systems to provide mote transmission capacity and shorter real-time transmission delay. However, FlexRay has many related parameters such as base cycle and slot lengths to be determined in the design stage. To assist vehicle network designers in configurationg a FlexRay network, this paper presents automatic field bus exchange format (FIBEX) generation method for migration from CAN message format such as CANdb to FlexRay FIBEX format.

A fully distributed event-triggered optimization scheme for optimal tire friction force allocation representing the core part of a feedforward control approach is proposed in this work. A standard projected subgradient algorithm involving consensus has been used for solving the resulting optimization problem. The triggering condition has been utilized to reduce the communication between the concurrent computing nodes primarily for facilitating real-time efficiency.

In this paper, we propose the control method of a writing robot for reproducing brush pressure and trajectory without force sensors. The main goal of this research is to estimate and save the brush pressure by using the internal model control. In order to evaluate the proposed controllers, the experimental device is developed. The paper shows that the proposed controller is able to reproduce the brush pressure on flat and inclined surface through experiments.

Traditionally Model Predictive Control (MPC) has been mainly restricted to processes with rather slow dynamics and with sampling times ranging from a few minutes to hours, such as the ones encountered in the areas of (petro)chemicals, minerals and metals. However, recent algorithmic advances (such as the explicit approach for MPC) allowed the application of MPC to problems arising in the automotive or power electronics industry where the time scales are in the milli-or even the microsecond area. In this study we aim to push the limit of explicit MPC even further by exploiting the computational power offered by parallel CPU architectures. We present the parallelisation of three different algorithms and we report experimental results showing how for certain problems, the parallelisation offers performances that top state-of-the-art approaches.

When artificial agents interact and cooperate with other agents, either human or artificial, they need to recognize others' actions and infer their hidden intentions from the sole observation of their surface level movements. Indeed, action and intention understanding in humans is believed to facilitate a number of social interactions and is supported by a complex neural substrate (i.e. the mirror neuron system). Implementation of such mechanisms in artificial agents would pave the route to the development of a vast range of advanced cognitive abilities, such as social interaction, adaptation, and learning by imitation, just to name a few. We present a first step towards a fully-fledged intention recognition system by enabling an artificial agent to internally represent action patterns, and to subsequently use such representations to recognize - and possibly to predict and anticipate - behaviors performed by others. We investigate a biologically-inspired approach by adopting the formalism of Associative Self-Organizing Maps (A-SOMs), an extension of the well-known Self-Organizing Maps. The A-SOM learns to associate its activities with different inputs over time, where inputs are high-dimensional and noisy observations of others' actions. The A-SOM maps actions to sequences of activations in a dimensionally reduced topological space, where each centre of activation provides a prototypical and iconic representation of the action fragment. We present preliminary experiments of action recognition task on a publicly available database of thirteen commonly encountered actions with promising results.

Flooding due to rivers overflowing have affected this year many countries in the world. The engendered problems, due to their intensity, are relative to goods and persons safety, and often cause a sharp increase of the insurance costs, which is no more tolerable in the actual economic context. To prevent these problems, it is necessary to limit water heights downstream the streams. In the literature, numerous described works were done on flows modelling and management. The work presented in this paper, is interested in the quantitative management by means of floods diversion areas placed along the river and for which location and sizing are known. A management method computing the height of gates opening at each time step is proposed. The strategy is based on a transportation network model of the flood diversion area system including the time transfer delays. It allows the computation of the water volumes to be stored in time. Simulation results for different flood episode are discussed.

In this paper, an algorithm based on the technique of variable switching frequency is applied, so that working point of boost converter is at the boundary between continuous and discontinuous working mode aiming at achieving maximum efficiency of the converter. Controller is based on variable switching frequency and measuring the voltage on the main converter switch. The proposed algorithm is verified by the simulations and experimental measurements on a converter prototype.

The approach for calculating the failure rate of a safety integrated circuit is used if the number of available test patterns is not sufficient. The safety integrated circuit can be structured in function blocks, that can be functionally compared to semiconductors with discrete structure. Failure models already known and applied for discrete semiconductors can be used to determine the failure rate of the individual function blocks. These models with their known failure rates serve as a reference for the safety integrated circuit function blocks. An advantage of this approach is that the internal safety integrated circuit structure can be taken into consideration when calculating the failure probability. The paper is based on the principles of the generic standard IEC 61508 Edition 2, 2010-04. Because new technologies lack field experience and a basis for evaluating certain risks, a conservative approach to determining failure rates has been emphasized as set forth in SN 29500.

With the encouraging rapid advancement in digital controller design, there is a need to explore further the optimal and robust digital controller implementation schemes. The ease in implementation of the discrete time controller urge the designers to adopt the emulation design technique, in which discrete-time systems are treated in a continuous-time framework. In emulation design, a discrete-time controller is obtained after the discretization of continuous-time controller at a high sampling rate. Keeping in view the valuable advantages of emulation design, a linear discrete time closed loop structure is proposed with emulation design based linear quadratic regulator (LQR). The suggested scheme provides optimal tracking of a reference signal even in the presence of external disturbances. Prior knowledge about the external disturbance is utilized by the control scheme to effectively minimize its effect on the system. Through computer simulations, a comparison is also drawn between the proposed emulation based control scheme and the corresponding continuous-time control scheme. Results shows that sampling time and weighing parameters of the cost function play important roles in defining the system performance.

This paper presents a novel analytical model for computation of the switched reluctance machine's (SRM) nonlinear magnetization characteristic and torque lookup table. The flux-tube and the gage-curve methods are used to develop the novel analytical model. Presented model is used for computation of the magnetization characteristic and torque lookup table of three and four phase SRMs. The simulation results obtained using proposed analytical model are compared to finite-element method (FEM) results. Experimental verification of the analytical model is presented for an 8/6 SRM.
