Pre-Processing of Data Coming From a Laser-EMAT System for Non-Destructive Testing of Steel Slabs

Abstract: Non-destructive test systems are increasingly applied in the industrial context for their strong potentialities in improving and standardizing quality control. Especially in the intermediate manufacturing stages, early detection of defects on semi-finished products allow their direction towards later production processes according to their quality, with consequent considerable savings in time, energy, materials and work. However, […]

Six Key Steps for an Effective Industrial Business Process Change

You probably use dozens of business processes every day. When processes work well, they can significantly improve efficiency, productivity, and customer satisfaction. You have also likely realized the results of inefficient processes that cause frustration, delays, and financial loss. That is why it is so important to improve processes that are not working well. Processes […]

Where Do Humans Fit in the Factory of the Future?

Much has been written and forecasted about the various impacts of technologies on humans: work, pleasure, productivity, and behaviors. The exponential growth of technical tools and their explosive applications to our lives have been nothing short of astounding. These have created an equally dramatic increase in new jobs with required skills. Organizations seek to fill […]

Implementation of a Soft PLC System Based on WorldFIP Fieldbus

Abstract: Communication efficiency is lowered and real-time performance is not good enough in discrete control based on traditional WorldFIP field intelligent nodes in case that the scale of control in field is large. A soft PLC system based on WorldFIP fieldbus was designed and implemented. Link Activity Scheduler (LAS) was integrated into the system and […]

How to Integrate Industrial and Information Networks

The benefits of converging industrial and information networks with a validated secure architecture based on standard Internet Protocol (IP) technologies are well established. The benefits include greater connectivity and integration across plants, easier data sharing across the enterprise, and better visibility into real-time operations. Bringing together information technology (IT) and operations technology (OT) networks is […]

Tracy-Widom Approach to F-16 Aircraft Sensor-Actuator Fault Detection

Abstract: The fault detection approach based on the Tracy-Widom distribution is presented and applied to the aircraft flight control system. An operative method of testing the innovation covariance of the Kalman filter is proposed. The maximal eigenvalue of the random Wishart matrix is used as the monitoring statistic, and the testing problem is reduced to determine […]

Event-Triggered Control Design of Linear Networked Systems with Quantizations

Abstract: This paper is concerned with the control design problem of event-triggered networked systems with both state and control input quantizations. Firstly, an innovative delay system model is proposed that describes the network conditions, state and control input quantizations, and event-triggering mechanism in a unified framework. Secondly, based on this model, the criteria for the asymptotical […]

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 […]
