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 […]

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 […]
