The article presents how three scaled down industrial machinery models were designed and built as an educational tool to present the transport of particulate material. The literature review showed calculation models for equipment at industrial level, not for laboratory level. There were chosen the most representative means of commercial transport for particulate materials: a conveyor screw, a conveyor belt and a bucket elevator. These three machines were calculated and built in polycarbonate to allow visualization of their internal functioning. The three devices are controlled by a programmable logic controller (PLC) and connected to each other by a SCADA network. The equipment is modular so as not to alter the order of operation, being able to obtain different work sequences. In addition, a man-machine graphic interface (HMI) was developed to supervise and to control the designed equipment. The results of particulate material mass flow obtained are approximately coincident with those estimated, validating the use of calculation models for much lower levels of work. Finally, it is emphasized that the system obtained is an environment for students to implement control techniques using the sensors and motors used in the designs.

Pneumatic Transfer System (PTS) is an auxiliary system of Ghana Research Reactor-1 (GHARR-1) used to transfer sample capsule in and out of the reactor irradiation sites. The PTS’ controller unit design and construction were carried out because the original transfer system was not designed to operate in cyclic NAA. To address these situations, a Programmable Logic Controller (PLC) has been used to design and construct a control unit to facilitate a cyclic neutron activation analysis (CNAA) application for GHARR-1. The design has been simulated successfully using a LOGO Soft Comfort software, version 8. The constructed control unit has been tested experimentally using 220 AC volts electric bulbs to represent solenoid valves. The results show that the sample-IN and sample-OUT bulbs come ON and go OFF to represent the solenoid valves opening and closing for sample transfer. The study has shown that the computer based PLC controller unit for PTS is capable of facilitating both cyclic and conventional NAA application for the GHARR-1.

A novel method for analogue VLSI implementation of programmable Gaussian function generator is proposed in this paper, in which the Gaussian function is approximated by the OTA-C filter whose frequency response is Gaussian-shaped. OTA-C circuit is very suitable for this application since the programmability can be controlled by the transconductance of OTA precisely and easily. Based on the probability argument, the OTA-C biquadratic filters and OTA-C integrator which have the cascade connection are used as the building block. To elaborate the construction procedure, a seventh-order OTA-C Gaussian function generator is selected as an example. The simulation results verify the feasibility of the presented approach.

This paper presents a design of a flow meter based on a programmable logic controller (PLC). The new construction of a flow meter controlled by PLC increases the possibilities for the control and automation of fluid flow. Additionally, the didactic potential of the use of simple automation in the form of a programmable logic controller was considered. A device enabling the measurement of fluid flow rate based on a PLC controller was designed, constructed, and tested. The choice of device was the Gems Sensors FT-210 series turbine flow sensor, which is characterized by low purchase and maintenance costs. The properties and the chemical resistance of polyamide-12, the material the sensor is made of, make it possible to test the flow of various types of fluids. As part of the work, an algorithm and a program controlling the device was developed based on the APB Soft software, enabling the accurate reading of the number of impulses sent by the turbine flow sensor. The results of the designed flow meter were compared with the results obtained for the Krohne VA-40 high accuracy rotameter.

A comprehensive test system for proton exchange membrane fuel cells (PEMFCs) is designed and developed for monitoring and controlling the inlet and outlet parameters and safety issues of fuel cells. The data acquisition and output instruction rely on the connection between PLC (programmable logic controller) and OPC (object linking and embedding for process control). Based on Siemens S7-200 series PLC and PID (proportion integration differentiation) technology, the margin of error in relative humidity of inlet air is controlled at less than 0.7%. Furthermore, a hydrogen recycling system and an alarm module are introduced, considering the hydrogen or nitrogen solenoid valve power failure, cooling fan power failure, temperature anomaly, and hydrogen leakage. This developed test system is evaluated by the experimental investigation of PEMFC performance. The results show that the test system has very good test and control performances. At a cell temperature of 40 °C, enhanced performance in the polarization tests is depicted at a high humidification temperature of 60 °C.

For monitoring the energy supply from the hybrid small-scale wind turbine generator (WTG) and rooftop solar Photovoltage (PV) systems, this paper presents the design of a management program of the studied system based on the Internet of Things (IoT) technology. The proposed studied system consists of digital power meters that communicate wirelessly to the Programmable Logic Controller (PLC) through the ZigBee communication standard. By using a free cloud platform will greatly facilitate the Supervisory Control and Data Acquisition (SCADA) interface design work for a Human Machine Interface (HMI) or mobile phone. This system configuration may be easy to be fitted for collecting electrical information such as voltage, current, power, frequency of the system to be monitored. This is one of the cheap solutions deployed in small-scale hybrid power systems (HPS) or factories because wireless communication is very convenient in construction and installation.

A new material testing reactor Jules Horowitz Reactor is under construction at CEA Cadarache. The materials to be irradiated will be placed into experimental devices around the reactor. Process and measurements of experimental devices will be carried out by command control. A data acquisition system having processing performances will be associated to the programmable logic controller. The challenge is to design and realize for twenty experiment devices a high availability data acquisition system architecture for 50 years of sustainability. The real time target will achieve 24/7 data acquisition and real time processing. This scalable architecture could be use as well for JHR experimental devices with high availability as for testbed. This architecture could be run on a standalone station for a measuring bench or deployed on cluster for high availability. CAREDAS’s design is modular and use proven widely used open source solutions. All parts are independent from each other and can be replaced with another technology with the same functionalities. This ensures sustainability and control of software sources.

The use of embedded Internet systems is growing rapidly in the manufacturing sector. These systems allow the monitoring and controlling of plant machinery and manufactured items from a remote location via a standard Web interface. In a manufacturing environment, it is inevitable that long running processes will require support for dynamic reconfiguration because, for example, machines may fail, services may be moved or withdrawn and user requirements may change. In such an environment it is essential that the operation and architecture of such processes can be modified to reflect such changes. This research project will present methods and ideas for establishing a reconfigurable remote system by using standard 8-bit microcontrollers and reconfigurable hardware. It will allow a manufacturing process to be modified and changed within minutes without even having to be physically present at the location where the process is running.

Water scarcity for agriculture is one of the most important challenges to improve food security worldwide. In this thesis we study the potential to develop a low-cost controller for a small scale brackish desalination plant that consists of proven water treatment technologies, reverse osmosis, cation exchange, and nanofiltration to treat groundwater into two final products: drinking water and irrigation water. The plant is powered by a combination of wind and solar power systems. The low-cost controller uses Arduino Mega, and Arduino DUE, which consist of ATmega2560 and Atmel SAM3X8E ARM Cortex-M3 CPU microcontrollers. These are widely used systems characterized for good performance and low cost. However, Arduino also requires drivers and interfaces to allow the control and monitoring of sensors and actuators. The thesis explains the process, as well as the hardware and software implemented.

Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2014.
The application of digital control techniques has become dominant in power electronics owing to several advantages they present, when compared to analogue solutions. Their development is based on the use of microprocessors and microcontrollers, such as Application Specific Integrated Circuit (ASIC), Digital signal processors (DSP), Field Programmable Gate Arrays (FPGA), or a combination of these devices. This thesis presents an investigation of a soft-core based FPGA control system as a solution for power electronic applications. The aim was the development and implementation of a conversion controller, which purpose is to supply control inputs in the form of digital Pulse Width Modulation (PWM) signals, to a number of power electronic applications, such as single half and full bridge DC-DC converters, three phase and multicell inverters. The PWM control technique is achieved via their power semiconductor switching devices. These PWM control signals are necessary for the high frequency conversion of an analog input voltage (AC, DC or unregulated) to an analog output voltage of another level (AC or DC). This was intended to be achieved by exploiting and combining the advantages that FPGA and embedded processors provide such as high reconfigurability and multipurpose ability. This controller’s digital outputs, namely PWM switching signals, can be directly delivered to an analog signal amplification circuit to create an adequate voltage level before being processed by the converters’ switches.

This thesis project presents the T-Sticks, a new family of digital musical instruments (DMIs). Most DMIs are either entirely unique interfaces, or exist as design iterations in which each incarnation is intended to improve on the last. The T-Sticks are instead intended to form a complementary group or consort which may be performed ensemble and also performed individually in solo pieces or works for mixed instrumentation. Each of the T-Sticks is based on the same general structure and sensing platform, but each also differs from its siblings in size, weight, timbre and register.
This document explores some of the issues challenging and motivating the field of DMI design and performance, and describes the motivations behind the T-Stick project in this context. Several existing DMIs are examined for similarities to the T-Stick and compared in terms of design intention, implementation, and usage. The hardware and software designed and built for this project is presented, along with insights gained through collaboration with performers and composers in the context of McGill University's Digital Orchestra project. The performers in question have collectively practiced and performed with the T-Stick for hundreds of hours in the lab, practice room, and on the concert stage. The consort of T-Sticks will be featured as an ensemble in a piece to be performed during the 2008 MusiMarch festival in Montreal.

The Programmable Logic Devices, PLO, have caused a major impact in logic design of digital systems in this decade. For instance, a twenty pin PLO device can replace from three hundreds to six hundreds Transistor Transistor Logic gates, which people have designed with since the 60s. Therefore, by using PLD devices, designers can squeeze more features, reduce chip counts, reduce power consumption, and enhance the reliability of the digital systems. This thesis covers the most important aspects of logic design using PLD devices. They are Logic Minimization and State Assignment. In addition, the thesis also covers a seldomly used but very useful design style, Self-Synchronized Circuits. The thesis introduces a new method to minimize Two-Level Boolean Functions using Graph Coloring Algorithms and the result is very encouraging. The raw speed of the coloring algorithms is as fast as the Espresso, the industry standard minimizer from Berkeley, and the solution is equally good. The thesis also introduces a rule-based state assignment method which gives equal or better solutions than STASH (an Intel Automatic CAD tool) by as much as twenty percent. One of the problems with Self-Synchronized circuits is that it takes many extra components to implement the circuit. The thesis shows how it can be designed using PLD devices and also suggests the idea of a Clock Chip to reduce the chip count to make the design style more attractive.

The development of energy efficient production systems such as machine tools is a complex process. All specialised departments must work interdisciplinary during the design process in order to achieve an optimal result. In addition to the mechanical aspects, e.g., lightweight construction, the optimization of the Programmable Logic Controller (PLC) programs of tooling machines plays an increasingly important role. By optimizing the programs in terms of energy efficiency, the energy consumption of a machine can be significantly reduced. However, energy consumption depends on many parameters, so the optimization process is complex and a matter of all engineering disciplines working together. By using Digital Twins of tooling machines, simulations can be used to perform many parameter studies for optimizing energy consumption. However, the generation of Digital Twins of production systems is very expensive if they are to represent all relevant features of a production system. Through an IT system of networked software programs and using AutomationML as a special data interface these Digital Twins of machine tools can be generated automatically. The article describes the structure and function of this IT system and how it will be efficient within all involved engineering disciplines.

The performances of System on Chip (SoC) and the Field Programmable Gate Array (FPGA) particularly, are increasing continually. Due to the growing complexity of modern embedded control systems, the need of more performance digital devices is evident. Recent FPGA technology makes it possible to include processor cores into the FPGA chip, which ensures more flexibility for digital controllers. Indeed, greater functionality of hardware and system software, Real-Time (RT) platforms and distributed subsystems are demanded. In this chapter, a design concept of FPGA based controller with Hardware/Software (Hw/Sw) codesign is proposed. It is applied for electrical machine drives. There are discussed different MultiProcessor SoC (MPSoC) architectures with Hw peripherals for the implementation on FPGA-based embedded processor cores. Hw accelerators are considered in the design to enhance the controller speed performance and reduce power consumption. Test and validation of this control system are performed on a RT motor emulator implemented on the same FPGA. Experimental results, carried on a real prototyping platform, are given in order to analyze the performance and efficiency of discussed architecture designs helping to support hard RT constraints.

The research presented in this chapter deals with the design and implementation of Real-Time (RT) control systems applying advanced Field Programmable Gate Array (FPGAs). The chapter proposes a promising flexible architecture that uses RT Operating System (RTOS) and ready-to-use Intellectual Properties (IPs). The authors detail an approach that uses software closed control loop function blocks (FB), running on embedded processor cores. These FBs implement the different control drive sub-modules into RTOS tasks of the execution environment, where each task has to be executed under well defined conditions. Two RTOSes are evaluated: µC-OS/II and Xilkernel. The FPGA embedded processor cores are combined with reconfigurable logic and dedicated resources on the FPGA. This System-on-Chip (SoC) has been applied to electric motors drive. A comparative analysis, in terms of speed and cost, is carried-out between various hardware/software FPGA-based architectures, in order to enhance flexibility without sacrificing performance and increasing cost. Case studies results validate successfully the feasibility and the efficiency of the flexible approach for new and more complex control algorithms. The performance and flexibility of FPGA-based motor controllers are enhanced with the reliability and modularity of the introduced RTOS support.

Long the iconic transportation symbol of Seattle, the monorail system was constructed for the 1962 World’s Fair. Seattle’s monorail vehicles were the last and most technically advanced vehicles designed and built by the firm of Alweg-Forschung, GmbH (Alweg) of Cologne, Germany. The primary train operating systems and components were supplied by major US transit system equipment vendors of that era, including G.E., WABCO, and Rockwell. The two, 4-car train’s original layout and function generally conformed to US transit rail equipment standards and design practices of the early 1960s. However, during 45-years of near-continuous, revenue operation that included upgrades, piecemeal refurbishment projects and accident/incident repairs, many changes were made to the original design with varying levels of success and documentation. In 2007, a small team of Seattle Monorail staff and consultants identified the vehicle systems and components that were most urgently in need of replacement or overhaul given the limited funding and time available for completion of design work, preparation of contractor bid documentation and construction. Project funding was primarily via a grant from the Federal Transit Administration (FTA), supplemented by the City of Seattle. The historical significance of the Seattle Monorail was at the center of the refurbishment program, with great care in functional design, aesthetics and construction being exercised throughout the program until completion in 2010. The modernization included the installation and integration of: communications-based train control; programmable logic controllers (PLC’s) for auxiliary systems; redundancy and interlocking of key safety-related components; streamlined controls that lead to significant weight savings and increased reliability; modern components to address ADA compliance; and ergonomic Driver Cabs. This report discusses the Seattle Center Monorail Refurbishment Program given the unique opportunity to modernize two historic pieces of transportation rolling stock that is anticipated to run in revenue service for the next 45 years.

Due to significant developments in power electronics since the 1980’s, a row of new components are being used for both utility [1] and traction power substations, leading to new concepts in their design and construction. Among others, such innovations as incorporation of microprocessor-based multifunction protective relays and programmable logic controllers are changing traditional substations’ equipment layout and inter-connections; the development and experimental use of thyristor rectifiers and solid-state DC circuit breakers is under way. A significant reduction in the amount of protective and control devices (and associated wiring) has been achieved by introduction of multi-function relays (MFR or MPR – Multi-Purpose Relay), capable of replacing a whole group of relays used for equipment protection and automated control; for example, one MFR may perform functions of overcurrent and ground fault protection, over- and undervoltage protection, fault sensing and reclosing. Plus, it may be used for data logging and data recording purposes [2]. Additionally, high end MPRs have remote access features allowing not only to set any parameters, but even provide firmware upgrade without visiting the substation, thus providing labor savings. Therefore, one MFR may replace about a dozen of traditional relays and devices, along with their wiring and save maintenance expenses as well. Thyristor Controlled Rectifiers (TCR’s) are another significant innovation in traditional DC traction power substation design. Thyristor rectifiers are offering very important benefit of regulated DC voltage: at the substation’s bus output, the voltage may be constant from 0 to a 100% or even 150% load, which means improved train performance in terms of speed and reliability, as well as lower losses of energy in third rails, and possibility of raising third rail system voltage in the future, thus further lowering losses of energy in the system. Alternatively, it allows to increase the distance between the substations and thus reduce total number of substations. LIRR installed one thyristor rectifier for experimental use in 2003. Flywheel-based energy storage system is another important innovation that is being installed by the LIRR for experimental use. LIRR is installing for experimental use trackside fly-wheel energy storage system developed and tested by the British uranium enrichment company URENCO. According to Tarrant [3], in March 2002 the company successfully tested the KESS – Kinetic Energy Storage System and demonstrated 11% to 18% energy savings in different conditions of operation, because of the lower losses due to higher voltage during the acceleration period.
