GRAphe Fonctionnel de Commande Etape Transition (GRAFCET) is a powerful graphical modeling language for the specification of controllers in discrete event systems and an international standard since 1988. It contributes to a more structural and model driven approach in the design of logic controllers but still lacks an exhaustive formal definition. As a step towards an exhaustive formal definition of GRAFCET this paper discusses time dependencies, as they are defined in IEC 60848, by comparing them to time constraints of timed Petri nets and Time Petri nets. Based on this analysis the authors propose an extension of a formal model for GRAFCET, which is a specific type of a control interpreted Petri net.
GRAphe functionnel de Commande Etape Transition (GRAFCET)是一种功能强大的图形建模语言，用于离散事件系统中的控制器规范，自1988年以来一直是国际标准。它有助于在逻辑控制器的设计中采用更结构化和模型驱动的方法，但仍然缺乏详尽的正式定义。作为对GRAFCET详尽的正式定义的一步，本文通过将它们与定时Petri网和时间Petri网的时间约束进行比较，讨论了IEC 60848中定义的时间依赖性。基于这一分析，作者提出了对GRAFCET形式模型的扩展，这是一种特定类型的控制解释Petri网。

This paper proposes a novel six-pulse-modulation (SPM) technique to switch voltage-fed dual front-end full-bridge converters in high-frequency three-phase inverter for rural electrification/islanded micro-grid/distributed energy resources (DER)/electric vehicles (EVs). High frequency pulsed dc voltage is produced by two full-bridge converters, summation of which results in 6-pulse waveform at 6x line frequency. This topology eliminates the need for dc-link capacitor which reduces the size and volume; it also helps in retaining the three-phase 6 pulse information at the input of three-phase inverter. Proposed SPM scheme achieves reduction in switching losses of the inverter devices. At any instant of line cycle, only two out of six switches are required to commutate at high frequency and remaining switches being retained at unique switching state. Moreover, devices are not switched when current through them is at its peak value. Drop in switching loss accounts to be around 21.7% in comparison with a standard voltage source inverter (VSI) switched using sine pulse width modulation (SPWM). Steady-state operation and analysis of the complete inverter system controlled by the proposed SPM along with its implementation has been explained. Complete inverter design has been presented. Analysis and design have been verified by simulation results using PSIM9.0.4 and experimental results on a developed and tested lab prototype of 1 kW have been demonstrated.

Engineering for lifecycle of products integrates all required definitions, descriptions, and simulations in contextual model spaces. Product Lifecycle Management (PLM) is flexible virtual technology to serve this new way of product engineering in company environments. Presently, communication between engineer and PLM modeling environment is done using product object generation processes where human defines features as objects. The well known and proven feature principle has been extended to the entire product model. It was first defined in the ISO10303 product model standard. A PLM system is open for extension by new features, procedures, and human communication surfaces in application environment opening the way also for research. As a contribution to research in open PLM environments, this paper introduces a novel knowledge based and product behavior driven human control of product object definition. Recent product modeling in PLM system handles contextual features including knowledge entities such as rule sets, etc. An actual problem in industrial engineering environments is that model of complex product includes huge number of feature and context definitions making communication of human with object generation very difficult. Contributing to a possible solution, this paper introduces an approach and method to replace the currently applied direct human control of product model object generation processes by a new objective and knowledge driven adaptive control. For this reason, the currently applied product model is proposed to extend by a new contextual chain including human request, product definition objective, product behavior, product object generation control, and product object model representation. The main essence of the proposed modeling is situation based product behavior feature driven definition of product objects as features. Situation connects specified product quality, knowledge for feature definition, and product features for requested product functions.

In this paper, a novel bearingless switched reluctance motor (BLSRM) with hybrid stator poles is proposed. The proposed BLSRM has short flux path and no flux reversal characteristics, and separated torque and suspending force control. The characteristics of the proposed structure are analyzed by finite element method. The analysis results show that the torque control can be decoupled from the suspending force control and the output torque is significantly improved when compared to the 8/10 hybrid stator pole type BLSRM. To verify the validity of the proposed structure, a prototype of the proposed BLSRM is designed and manufactured. Meanwhile, a control scheme is proposed based on the novel structure. In the scheme, a simple PID and hysteresis current control methods are employed. The validity of the proposed structure and its control scheme are verified by the experimental results.

This paper investigates the efficacy of several popular denoising methods in the previously unconsidered context of Computed Tomography (CT) baggage imagery. The performance of a dedicated CT baggage denoising approach (alpha-weighted mean separation and histogram equalisation) is compared to the following popular denoising techniques: anisotropic diffusion; total variation denoising; bilateral filtering; translation invariant wavelet shrinkage and non-local means filtering. In addition to a standard qualitative performance analysis (visual comparisons), denoising performance is evaluated with a recently developed 3D SIFT-based analysis technique that quantifies the impact of denoising on the implementation of automated 3D object recognition. The study yields encouraging results in both the qualitative and quantitative analyses, with wavelet thresholding producing the most satisfactory results. The results serve as a strong indication that simple denoising will aid human and computerised analyses of 3D CT baggage imagery for transport security screening.

A high performance class-AB CMOS second generation current conveyor (CCII) suitable for low-power and low-voltage operation is proposed and simulated. The circuit is aimed to be used for sensor signal conditioning and it is based on the flipped voltage follower. Compared to the class-A CCII based on the flipped voltage follower, static power consumption is reduced significantly because driving capability is no longer limited by the biasing current, but only depends on the aspect ratio of the transistors driving current at nodes X and Z. All the high performance characteristics such as accurate voltage copy between X and Y terminals, low output impedance, high input impedance, low total harmonic distortion and wide bandwidth are retained. A modified structure with improved dynamic range for higher voltage supplies, based on the folded version of the flipped voltage follower called super source follower, is also presented. Simulation results demonstrate performance of the proposed designs.

Fractional-order PID controller (FOPID) design and implementation is one of emerging research areas. This paper presents a method for computing generalized robust stability regions in controller parameter plane. The method can cope with arbitrary linear process model of integer or fractional order. It allows to fulfill essential frequency domain design specifications, namely gain and phase margins, closed loop bandwidth, etc. Further, it can operate simultaneously with number of processes hence can work with uncertainty given e.g. by model set or by parameter intervals. Moreover, the regions can be computed even for selected filter in derivative part of the FOPID controller. The method described is partly available in the interactive Java applet freely accessible at www.pidlab.com. The illustrative example demonstrates that FOPID controller can fulfill stricter design specifications compared to traditional PID.

Regular Sampling is the state of the art when employing digital discrete-time control to pulse width-modulated systems. However, the fact that the dynamics of discrete-time control is below that of an analog continuous-time control is often not being aware. The paper shows that digital control dynamics can be improved with oversampling, i.e. employing a higher rate for sampling and controller updating as with Regular Sampling without increasing the pulse frequency. As a result, it is shown that already an oversampling rate of about 8 to 16 provides approximately the same dynamics of a continuous-time control. The benefits of even higher oversampling rates are of minor significance, which can be understood as a clear design recommendation. Though the consideration is carried out with a simplified circuitry, the results are of general meaning and can be transferred easily to application in the area of drive control or switched-mode power supplies.

A high-power ultrasonic transmitter that employs an array of transmitting elements is investigated theoretically. It is used in a range sensor system using pulse-modulated ultrasonic waves. The sound pressure and directivity are investigated theoretically. Increasing the number of elements, increases the sound pressure, enabling a higher power to be obtained. However, it increases the directivity. The influence of pulse modulation is also investigated; short pulse modulation was found to alter the pulse shape.

Due to the availability of efficient three-phase inverters, Permanent Magnet Synchronous Motors (PMSM) have become an interesting drive concept for numerous applications. However, for efficient and smooth operation, the inverter input switching signals have to be modulated in a suitable way in order to obtain an appropriate commutation sequence for operating a PMSM. Besides of the well-known and commonly applied Pulse-Width-Modulation (PWM) techniques, Delta-Modulation and Delta-Sigma-Modulation (DSM) techniques have been proposed in literature for driving inverters. This paper investigates the suitability of such DSM techniques for modulating two-stage and three-stage inverters for PMSM applications.
