April Training and Education Programs from ISA

April training and education programs from ISA feature several special events such as the popular Automation Engineering Survival Training course (in Columbia, Ill.) and the Process Automation Boot Camp (in Research Triangle Park, N.C.). ISA’s Automation Engineering Survival Training course is designed for system integrators and focuses on concepts important to automation engineers and others […]

Maximizing Production Rate of Single Phase Liquid Reactors

The control scheme commonly used by gas reactors that inherently maximizes production rate cannot be effectively used by liquid reactors. The optimization of production rate can be achieved by the simple configuration of a PID loop that uses existing signals. However, special PID features must be used to prevent oscillations and to deal with unmeasured […]

Process Control Systems for Industrial Applications

Recently, the International Electrotechnical Commission (IEC) approved a new standard for the specification and evaluation of process control systems (PCSs) in industrial applications: IEC 62603, “Industrial Process Control Systems – Guideline for Evaluating the Performances of Process Control Systems – Part 1: Specifications.” The process of specifying, choosing, and testing a process control system for […]

Stabilization and Tracking Control of X–Z Inverted Pendulum with Sliding-Mode Control

Abstract: X–Z inverted pendulum is a new kind of inverted pendulum which can move with the combination of the vertical and horizontal forces. Through a new transformation, the X–Z inverted pendulum is decomposed into three simple models. Based on the simple models, sliding-mode control is applied to stabilization and tracking control of the inverted pendulum. […]

How to Change Thinking Patterns to Generate New Ideas

Are you stretching your thinking beyond the obvious to find new solutions? We have a tendency to use the first workable idea when trying to make something work, fix a problem, or make an improvement. This has been described as “satisficing,” where we try alternatives until an acceptable solution is found and then stop looking […]

Achieving Tight Control of Single Phase Liquid Reactors

Well-mixed liquid reactors have dynamics that offer the possibility of extremely tight control of product composition but lack some of the self-regulation in multiple phase reactors achieved by inventory control. For a reactor to achieve its full potential requires an intelligent design of the control strategy. Here we look at how to set up the […]

The Internet of Everything Delivers Smart Manufacturing

The Internet of Everything (IoE) is here now. Today it is estimated that manufacturers generate 2 exabytes of information daily—resulting in more “big data” than any other industry or sector. And when you consider that only 4 percent of the devices on the manufacturing floor are actually connected to a network, we can expect to […]

Multivariable Control Performance: A Case for Model-less Control

Multivariable control is usually thought of as a product of the computer age, but multivariable control has always been an integral part of industrial process operation. Before the computer era, the operating team did multivariable control manually, by adjusting the available controllers and valves to keep related process variables within constraint limits and to improve […]
