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 […]

ISA Technical Education and Training for September and October

In September, drill down on process control with ISA’s Process Automation Boot Camp. Designed for non-maintenance personnel with little or no background in process measurements and control, this hands-on course focuses on the physical measurement technologies, the communication signals, and various applications of instrument equipment to achieve common process measurements and control. An exciting mix […]

How Does Low Flow Affect Differential Pressure Flowmeter Calibration?

For flowmeter calibration, the phenomenon of “low flow cut-off” is only associated with differential pressure transmitters with square root extraction — if the square root (flow) calculation is done in the control system (DCS/PLC), then this test approach does not apply. The graphic below illustrates the issue. Some may ask why we are testing the […]

The Decision to Volunteer: The Why, How, and a Personal Call to Action

In their book, The Decision to Volunteer: Why People Give Their Time and How You Can Engage Them, Beth Gazley and Monica Dignam used research on associations to better understand why members volunteer for professional societies such as ISA.  Their research indicated that volunteers contribute their time for both altruistic (other-serving) and instrumental (self-serving) reasons.  […]

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 […]

Steps You Can Take to Help Close the Industrial Skills Gap

If you’re like most manufacturers, your most experienced employees are also those closest to retirement. Replacing them without creating quality gaps won’t be easy or cheap – studies show that without a proper knowledge transfer plan, the cost to replace a senior engineer is between 300 percent and 500 percent of the senior employee’s salary. […]

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 […]

How Can ISA Best Meet My Needs?

How can ISA help me?  This is a question we hear from automation professionals, members, and volunteer leaders.  As a section leader, it is a question that I have also asked in the hope of helping me better perform my volunteer role.  There is no simple one-line answer, but let me provide a few common […]

Increasing Diversity in the Automation Profession

There have been many articles written on how and why we should increase the number of individuals from minority groups in the field of automation. Most reflect the opinions of diversity experts or human resources professionals, and some are politically motivated. This article is different because it gives the opinions of minority participants actively working […]
