Multi-Objective Control of Nonlinear Boiler-Turbine Dynamics

Abstract: This paper investigates multi-objective controller design approaches for nonlinear boiler-turbine dynamics subject to actuator magnitude and rate constraints. System nonlinearity is handled by a suitable linear parameter varying system representation with drum pressure as the system varying parameter. Variation of the drum pressure is represented by suitable norm-bounded uncertainty and affine dependence on system matrices. […]

Plant Historians Deliver Insight and Improve Operations

Plant historians became popular in process plants in the 1980s. More recently they are being used broadly throughout industry to improve operations, identify problems, and find opportunities for enhancement. An early forerunner of historians were electromechanical pen-and-paper chart recorders. They produced a graph of one or more measured values over a period of time for […]

Remotely Managed Industrial Automation Cybersecurity

Epic Turla, Regin, and BlackEnergy are the names of just a few in a series of recent malware discoveries that target industrial automation control systems (IACS). The increasing volume and sophistication of these types of threats has driven the topic of operational technology security all the way up to the corporate boardroom. Unfortunately, the attack […]

How to Prevent the Skilled Worker Shortage From Slowing Manufacturing Momentum

Over the past decade, the manufacturing renaissance has been a driving force in the country’s economic recovery. And it makes sense — after all, every dollar spent in manufacturing returns $1.37 to the economy, and every 100 new manufacturing jobs creates an additional 250 jobs in other sectors. Yet even as the industry continues to […]

Is Social Media & Content Marketing ‘Business as Usual’ for Industrial Automation?

In a previous post, I shared the results of a survey that found the industrial automation and control industry was behind the curve when it comes to digital marketing, website optimization and other current online marketing strategies. If you’ve worked as a marketer in the automation, control and manufacturing sectors during the evolution of the […]

Plant-Wide Control: Eco-Efficiency and Control Loop Configuration

Abstract: Since the eco-efficiency of all industrial processes/plants has become increasingly important, engineers need to find a way to integrate the control loop configuration and the measurements of eco-efficiency. A new measure of eco-efficiency, the exergy eco-efficiency factor, for control loop configuration, is proposed in this paper. The exergy eco-efficiency factor is based on the thermodynamic […]
