Automatic Subsea Blowout Preventer Stack Control System Using PLC-based SCADA

Abstract: An extremely reliable remote control system for subsea blowout preventer stack is developed based on the off-the-shelf triple modular redundancy system. To meet a high reliability requirement, various redundancy techniques such as controller redundancy, bus redundancy and network redundancy are used to design the system hardware architecture. The control logic, human-machine interface graphical design and […]

Simultaneous Gains Tuning in Boiler-Turbine PID-based Controller Clusters

Abstract: Tuning a complex multi-loop PID based control system requires considerable experience. In today’s power industry the number of available qualified tuners is dwindling and there is a great need for better tuning tools to maintain and improve the performance of complex multivariable processes. Multi-loop PID tuning is the procedure for the online tuning of […]

How to Improve Industrial Automation Security

The history of industrial automation fascinates me. Continuous innovation and new technologies have taken manufacturing processes that originated in the Industrial Age and catapulted them straight into the information age. Just as productivity seemed to be topping out, the Internet helped boost productivity and efficiency to previously unimaginable levels. Unfortunately, as industrial automation roared into […]

Opto-Isolator Based Linearization Solution for a Thyristor-Driven Pump

Abstract: A thyristor driven pump is operated by varying the DC input signal in the firing circuit of thyristor drive. This operation suffers from difficulties due to the nonlinear relation between thyristor output and DC input. In the present paper, an opto-isolator based linearization technique of a typical thyristor driven pump has been proposed.   The […]

Improved Correlation Analysis and Visualization of Industrial Alarm Data

Abstract: The problem of multivariate alarm analysis and rationalization is complex and important in the area of smart alarm management due to the interrelationships between variables. The technique of capturing and visualizing the correlation information, especially from historical alarm data directly, is beneficial for further analysis. In this paper, the Gaussian kernel method is applied to […]

New Industrial Standards for Robotic Safety

The past few years have been marked by significant changes in industrial safety standards in the U.S. Safety managers, plant managers, and others who are not carefully monitoring these developments may not be keeping pace with the latest codes and regulations. According to the Occupational Safety and Health Administration (OSHA), “machine guarding” that pertains to […]

Modular Systems Speed and Simplify New Plant Programming

Getting out the cake and candles may have been overdoing it, but ISA-88’s 20th birthday was 28 February 2015. Since 1995, it has served countless manufacturers, primarily in batch process industries, while growing and evolving to cover new areas, and even spawning other standards. The first batch control standard in the ISA-88 series was approved […]

How to Achieve More Value from Your Automation Projects

The industrial automation industry is largely a project-centric business. Over the past three decades automation suppliers, system integrators, engineering procurement contractors, and industrial automation users have become extremely proficient at executing automation projects. Unfortunately, in numerous interviews in which I have participated with industrial company executives, many indicated that although they believe automation should add […]
