Leveraging Industry Silos to Develop New Business Opportunities

There has been a great deal of discussion about isolated silos in industry creating barriers to growth, but they also offer opportunities for those willing to take the initiative. The term silo thinking is used in business to describe the mindset when departments do not share information and collaborate with others in the same company. […]

Integrating DCS I/O to an Existing PLC

At the NASA Glenn Research Center (GRC) in Cleveland, Ohio, existing programmable logic controller (PLC) input/output (I/O) was replaced with distributed control system (DCS) I/O, while keeping the existing PLC sequence logic. Until about the year 2000, the GRC’s central process system (CPS) distributed control system used PLC I/O to remotely control and monitor process […]

Finite-Time Control for Nonlinear Spacecraft Attitude

Abstract: In this paper, a fast terminal sliding mode control (FTSMC) scheme with double closed loops is proposed for the spacecraft attitude control. The FTSMC laws are included both in an inner control loop and an outer control loop. Firstly, a fast terminal sliding surface (FTSS) is constructed, which can drive the inner loop tracking-error […]

What are the Implications of Reactor Type on Control?

Reactors involving liquid reactants can be categorized as continuous stirred tank reactors (CSTR), batch, fed-batch (semi-batch or semi continuous), and plug flow. In continuous reactors, there is a continuous discharge of product flow. A level controller is used in the CSTR to maintain a level that provides enough reaction time for a given production rate. […]

Industrial Automation and Embedded Vision: A Powerful Combination

In order for manufacturing robots and other industrial automation systems to meaningfully interact with the objects they are assembling, as well as to deftly and safely move about in their environments, they must be able to see and understand their surroundings. Cost-effective and capable vision processors, fed by depth-discerning image sensors and running robust software […]

Listen, Celebrate, Recognize – The 2014 ISA Hall of Fame

Involve everyone in everything… “Wholesale involvement is necessary to engender the level of quality, service, and flexibility required by today’s markets. Intense communication is required to foster that involvement; we must: Listen constantly, congregate, or share ideas/information, and recognize achievement Celebrate –informally and formally–the “small wins” that are indicative of the solid day-to-day performance turned […]

Mobile HMI Technology Enters a New Era

A significant shift is occurring in the automation world: the PC, while still an important element in the technology   mix, is no longer the dominant method for remotely accessing automation systems. This is the result of changes in technology and business practices. The Great Recession precluded many companies from hiring additional staff, making them do […]

Global Adaptive Output Feedback Control for a Class of Nonlinear Time-Delay Systems

Abstract: This paper addresses the problem of global output feedback control for a class of nonlinear time-delay systems. The nonlinearities are dominated by a triangular form satisfying linear growth condition in the unmeasurable states with an unknown growth rate. With a change of coordinates, a linear-like controller is constructed, which avoids the repeated derivatives of […]
