Abstract:

A high reliability, flexible reactive power automatic compensation controller based on PLC is designed, which the structure and principle of the system is explicitly specified. The controller adopts commercial PLC as the control core,TD400C as human-machine interface, and uses ABB RVT-6 power factor controller to control the switching of the capacitor. Blocking structure is used to design software, whose structure is clear and easy to debug and modify. Running result obtained from relevant application describing the novelty of reactive power compensators implemented with new technologies is also described.

Abstract:

Successful controller development involves three distinct stages, namely, control law design, code debugging and field test. For Autonomous Underwater Vehicle (AUV) applications, the first two stages require special strategies. Since the dynamics of an AUV is highly nonlinear, and the environment that an AUV operates in is noisy with external disturbance that cannot be neglected, a robust control law must be considered in the first stage. The control law design is even more difficult when optimal criteria are also involved. In the second stage, since the software architecture on an AUV is very complicated, debugging the controllers alone without all the software routines running together often can not reveal subtle faults in the controller code. Thorough debugging needs at-sea test, which is costly. Therefore, a platform that can help designers debug and evaluate controller performance before any at-sea experiment is highly desirable. Recently, a 6 Degree of Freedom (DOF) AUV simulation toolbox was developed for the Ocean Explorer (OEX) series AUVs developed at Florida Atlantic University. The simulation toolbox is an ideal platform for controller in-lab debugging and evaluation. This paper first presents a novel robust controller design methodology, named the Sliding Mode Fuzzy Controller (SMFC). It combines sliding mode control and fuzzy logic control to create a robust, easy on-line tunable controller structure. A formal proof of the robustness of the proposed nonlinear sliding mode control is also given. A pitch and a heading controller have been designed with the presented structure and the controller code was tested on the simulation software package as well as at sea. The simulated and at-sea test data are compared. The whole controller design procedure described in this paper clearly demonstrates the advantage of using the simulation toolbox to debug and test the controller in-lab. Moreover, the pitch and heading controller have been used in the real system for more than 2 years, and have also been successfully ported to other types of vehicles without any major modification on the controller parameters. The similarity of the controller performances on different vehicles further demonstrates the robustness of the proposed Sliding Mode Fuzzy Controller. The main contribution of this paper is to provide useful insights into the design and implementation of the proposed control architecture, and its application in AUV control.

Abstract:

Urgency of the research. Programmable logic controller are devices for controlling of various systems also in industry. If controlled device is complicated, it is problem to debug application, because of risk of its damage. For this purpose is better to use hardware training stand for testing of your designed application. Target setting. Training stand is as compact small device which is easy to move to another place. Also it allows to connect other hardware device for testing. Logical state hardware simulator is also designed for simulation of logic system with any user inputs with buttons or switches and also witch coloured lights for visualisation of output state.Actual scientific researches and issues analysis. Training set allows to make simulation of control system with real parts before its practical use with expensive controlled system, where any mistake can cause a huge economist loses, but errors occurred during the simulation on training set only make warning and shows the weak place on design. Uninvestigated parts of general matters defining. The questions of the networked structure of programmable logic controller structures are uninvestigated, so the next research will be focused to this. The research objective. The main goal is to create a compact device for training future application developers with a programmable logic controller, but it is also usable for developers from practice, who need to debug the program before installing it into real operation. The statement of basic materials. Existing training sets are large and expensive devices that are not easy to carry and cannot be expanded. Working with such devices is quite complicated. The designed training stand is a flexible and easily portable device. Conclusions. Main contribution is that students will gain practical experiences and skills that are essential for PLC programmers. This device supports also own creativity of students, because it allows to modify hardware composition. It uses the DIN rail system similar as in real installation cabinet. The stand also includes the human-machine interface for training of practical using of these devices.

Abstract:

PAC(programmable automation controller) is a new trend of the industrial controller, but for now, most IDEs(integrated development environment) are still providing the PLC mode for users, which can not take full advantage of the PAC. Further more, in China, there is still not such IDE with complete intellectual properties for PACs designed by Chinese companies. For above purposes, the CHD-PACIDE was implemented which supported the ARM cortex-Mx series microcontrollers. This IDE consists of three layers, interface layer, data management layer and kernel layer, which managed functional modules respectively. Based on a C-like language Engineer C defined by our research team, the interface layer provided the structural graphical input mode and the text input mode for users to edit their code. The data management layer used the XML with specified format manage the flow of data. The kernel layer had two parts which were implemented in the IDE and the debug microcontroller stm8s, this layer can be used to debug user’s code through the Jtag port under the Coresight debugging structure of ARM. This IDE could be updated easily by adding the specific XML file for the new microcontroller used by the specific PAC.

Abstract:

Verification is considered a critical stage of any chip development cycle. This step ensures that the design meets the system requirements and specifications. At this stage, test cases are developed, and the invention's functionality is checked. But it is supposed that Verification takes almost 60% of the total chip development chip cycle. It makes it a critical stage in any chip flow since any bug found post routing is a bit tough to remove, and also, post-fabrication, it is challenging to correct the design. The project focus on improving the efficiency of verification cycle. It can be achieved by introducing a Debug Checker in the Testbench itself, which reduces verification time many folds. The project targets segregating the potential bug region once any mismatch or error is found in Testbench.

Abstract:

Ever since life’s debut on the earth, biotic evolution has been a near-balancing act. On virtually every level, competition and cooperation, shifting endlessly between foreground and background, have tugged and teased evolving systems as they have wobbled through time along the edge of chaos. The emergence of cellular life from the world of complex carbon-based chemistry appears to have happened only once in the primordial dreamtime of planet Earth. Scientists base this conjecture on a number of virtually universal distributions of chemical structures and processes across the spectrum of living organisms. Despite their perhaps tenuous hold on life, the earliest cells, primitive bacteria and archea, possessed the keys to the opening of new potential for matter and energy—the capabilities of self-replication, controlled energy transduction, directed locomotion, and the regulation of an internal environment. Out of this cellular Big Bang there arose a totally new force field on planet Earth superimposed over the physical, chemical, and geological, but with tendrils pervading all of those realms. It was the beginning of the biosphere. Life pervaded and began to transform the lithosphere, hydrosphere, and atmosphere. The chapter highlights transitions of prokaryote to eukaryote via endosymbiosis. Also featured are: biofilms, bioluminescence, coral reefs, and ecological succession.

Abstract:

In February 1971, while her studio-seized debut feature A New Leaf was being readied its premiere, Elaine May took a job-for-hire – adapting Lois Gould's newly published, fictionalized semi-memoir Such Good Friends for director Otto Preminger. Her work on the film was pseudonymously ascribed to Esther Dale, in keeping with May's general policy of not taking credit for projects for which she lacked authorial control, and has tended to be regarded as little more than a footnote in her career. Yet Such Good Friends is characterized by themes and styles which typify May's oeuvre: betrayal of a partner; the conflict between the roles we play and our ‘true’ selves; abrupt, seemingly spontaneous, tonal shifts; a particularly intellectual, highly verbal brand of New York Jewish humour counterpointed by vulgar farce; the spectre of impending death. Further, the film shows us that, even when working as intermediary between Gould and Preminger, May's outlook remains thoroughly existentialist. This philosophy, popularized by Jean-Paul Sartre, is not merely reflected in the content of her work but also shapes her entire approach to creative endeavours. Indeed, it's fascinating to see how May's inherent spontaneity, manifested as an inescapable subjectivity, merges with Preminger's highly- controlled, deliberately composed objectivity.

Abstract:

“Home on the Range” evokes a western landscape “where the deer and the antelope play.” But even at the song’s debut in the 1870s, deer and antelope were declining in numbers and cattle grazing was degrading rangelands across the American west. In their natural state, arid North American lands are robust and productive, but they recover exceedingly slowly from heavy grazing. By 1860, more than 3.5 million domesticated grazing animals were trampling arid western soils, causing severe erosion and lowering both water quality and water supplies in a water-poor region. The early start and persistence of grazing over such a long period of time invaded every nook and cranny of the public lands, making livestock grazing the most pervasively damaging human land use across all western ecosystems. Today, grazing affects approximately 260 million acres of publicly owned forest and rangelands, mostly in the 11 western states—about equivalent to the combined area of California, Arizona, and Colorado. Those acres include Pacific Northwest - r and ponderosa forests; Great Basin big sagebrush lands; the richly H oral Sonoran Desert; magni- cent high-desert Joshua tree forests; varied shrub associations in the low-elevation Mojave, Great Basin, Chihuahuan, and other southwestern deserts; and extensive Colorado Plateau pinyon–juniper forests stretching from northern Arizona and New Mexico to southern Colorado and Utah and decorating the arid inland plateaus of Washington, Oregon, and northeastern California. Proponents of public lands grazing argue that cattle have not changed anything. They just replace the immense herds of hooved native herbivores—bison, deer, antelope, and elk—that once dominated western ranges. But in pre-European settlement times, natural forces, including unlimited predators and limited fodder, effectively controlled the native animal populations. Unlike cattle, the herds of deer, antelope, and elk wintered in generally snow-free lowland areas and used much less than their full range each year. And those animals were easier on the land, especially the rivers. Immense bison herds ranged over vast areas, never staying very long on any range. Bison rarely visited the sites of today’s major livestock grazing problems in Great Basin and southwestern deserts, however. On northern ranges, bison obtained winter moisture from eating snow and did not cling to creeks and streams the way cattle do.

This article presents the results of the simulation model of a transport robot based on a digital linear-quadratic controller with state feedback for systems with discrete time and state space (DLQR controller), such as: modeling the state matrix, an example of the operation of a DLQR controller with visualization trajectory of the transport robot. The transport robot is an object with an installed brushless DC motor (BLDC motor), controlled by the electrical circuit of the H-bridge, and a stationary camera for orientation in space. The hypothesis of the scientific novelty of the main result is to increase the efficiency of the control system by switching from vector control to the theory of optimal control, since vector control is not optimal, using a DLQR controller. Currently, a previously known route is used to demonstrate the operation of the DLQR regulator. This decision was made to debug the simulation model.

Abstract:

Abstract The extensive use of planarization in many of today's leading process technologies significantly reduces the effectiveness of FIB circuit modification and debugging. Planarization has played a significant role in the development of denser chips with increasingly smaller geometries. Fully planarized devices offer little or no surface features on which the FIB operator relies for orientation and alignment. These conditions lead to increased debug cycle times and decreased success rates using the FIB. Recent FIB tool advancements in the field of C4 (controlled-collapse chip connection) flip-chip packaged device modification and debug have also made it easier to work on highly planarized conventional wire-bond technology. The integration of an optical microscope with an infrared camera into the work chamber allows the operator to view the circuitry under the surface layer. This paper will offer several techniques for overcoming the challenges that planarized devices present by using this in-situ optical microscope. When properly implemented, these techniques can significantly improve the success rate and throughput time of device modification on highly planarized parts.

Full text

Abstract:

Many degree courses at technical universities include the subject of control systems engineering. As an addition to conventional approaches Fuzzy Control can be used to easily find control solutions for systems, even if they include nonlinearities. To support further educational training, models which represent a technical system to be controlled are required. These models have to represent the system in a transparent and easy cognizable manner. Furthermore, a programming tool is required that supports an easy Fuzzy Control development process, including the option to verify the results and tune the system behavior. In order to support the development process a graphical user interface is needed to display the fuzzy terms under real time conditions, especially with a debug system and trace functionality. The experiences with such a programming tool, the Fuzzy Control Design Tool (FHFCE Tool), and four fuzzy teaching models will be presented in this paper. The methodical and didactical objective in the utilization of these teaching models is to develop solution strategies using Computational Intelligence (CI) applications for Fuzzy Controllers in order to analyze different algorithms of inference or defuzzyfication and to verify and tune those systems efficiently.

Abstract:

Abstract This electrical fault isolation based on Xilinx 28nm all programmable device in a Distribution RAM (LUTRAM) functional block. The Look-Up-Table (LUT) was the major component to achieve the programmable chip versus the ASIC chip. In the device architecture, one 6-inputs-LUT (LUT6) memory can be configured as a 64bits distribution RAM (LUTRAM64) or two 32bits distribution RAMs (LUTRAM32). The Vivado design and debug tool brought up two powerful Intellectual Property (IP) Cores: Virtual Input/Output (VIO) and Integrated Logic Analyzer (ILA). This debug tool used Block RAM (BRAM) and fabric routing resources to store the full test results and achieved package level probe-less. [1] It can probe LUTRAM block input, output and Build-In Self-Test (BIST) interconnects. However the limitation was that the inner primitive functional block LUTRAM like memory cells, decoders, mode switchers, write/read controllers and so on were not able to probe. In this case study, the defect was not conventional failure inside the LUTRAM memory cell or stuck on Address/Data_in inputs. Moreover the test behavior with LUTRAM64 mode had conflicting results, which made the fault isolation even more challenge to narrow down from complex LUTRAM control circuitry to transistor level. Therefore different pattern test methodologies, pattern commonality analysis and hypothesis verification were wisely compiled together. In the end, the defect was successfully localized at the fault Isolation circuitry. It was fully matching with the failing mode and proving the fault isolation was correct. The physical defect analysis shown multiple layers metal fusing. The defect shorted the internal control output with the GND signal, which forced LUTRAM to setup as an invalid mode.

In 2000 3rd International Pipeline Conference. American Society of Mechanical Engineers, 2000. http://dx.doi.org/10.1115/ipc2000-240.

Full text

Abstract:

Recent advances in PLC, SCADA and leak detection system technologies lead to the development of a highly integrated control system. Interconnected with fiber optic communication speeds (OC-1), this level of integration moves away from the historic model of stand-alone field controllers connected over low speed communication links to a centralized control center which, in turn, exchanges data from the host system to stand-alone leak detection processors. A new system design approach utilized familiar pipeline control elements such as PLC controllers and MODBUS communication protocols in combination with elements more typically associated with an office environment such as Windows NT servers, PC compatible computers, and Ethernet TCP/IP communications networks. These open-architecture components were used to fully develop, debug and test the SCADA system prior to system startup. The pipeline simulator is used as the centerpiece for this process to perform thorough operational validation of the system long before initial linefill. Once the various components were fully tested they were exported to the physical system in an operational state. The result is nearly seamless control systems supported by high data rates, high model speeds, common databases, and multi-channel communications. The increased level of integration has had dramatic impacts in leak detection, system safety, engineering development, operator training, and overall reliability of the control systems. The following paper presents a narrative overview of these new developments in the context of an implementation on Pacific Pipeline System (PPS). PPS is a recently constructed and commissioned 209 km (130 mile), 50.8 cm (20″) diameter, hot crude oil pipeline between the southern portion of California’s San Joaquin Valley and refineries in the Los Angeles basin. Following the Interstate 5 corridor over the “Grapevine”, Tejon Pass, Angeles National Forest and through heavily populated areas, this pipeline traverses some of the most environmentally and safety sensitive regions in the United States. The joint federal and state Environmental Impact Report / Environmental Impact Statement (EIR/EIS) set high hurdles for leak detection and control system performance. The historic control architecture and technologies were not adequate. This paper provides an overview of the environmental and physical constraints of the Pacific Pipeline System alignment, hydraulics, pumping and metering equipment, and block valve locations. It also discusses their impact on the design, programming and commissioning of a SCADA system meeting the requirements of the EIR/EIS. The paper then describes in more detail the fiber-optic communication system, control system architecture, SCADA system, leak detection models, simulator models and implementation methods, along with the engineering decisions leading to a comprehensive solution for the SCADA and leak detection requirements.
