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 […]

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 […]
