Control Engineering Leaders Under 40 is a recognition program designed to identify and give recognition to young engineers who have made significant contributions toward the control engineering profession. The goal is to get more young people interested in engineering. For this recognition, we seek successful and well-rounded control-engineering-minded individuals 18 or older and under 40 years of age.
Vote now! Control Engineering Engineers’ Choice Awards highlight some of the best new control, instrumentation and automation products as chosen by Control Engineering’s print and online subscribers. Subscribers to the North American print and digital editions are asked to select the best products based on technological advancement, service to the industry, and market impact.
Product Exclusive: CFE Media’s Apps for Engineers software is an “app of apps,” providing an interactive directory of approximately 60 mobile engineering-related software applications useful for Control Engineering, Plant Engineering, and Consulting-Specifying Engineer areas of coverage.
But meeting a specific performance measure is harder than it looks.
Inside Machines tips and tricks: Control engineers need to practice these programming tips to ensure project timeline pressure doesn’t harm the machine project.
These 100 firms represent the largest system integrators of 2012, from among 2,334 in the Control Engineering Automation Integrator Guide.
Making fieldbus projects as painless as possible – Designing and implementing a successful—and painless—fieldbus project requires mapping out network requirements as well as understanding the plant’s information, diagnostic, and maintenance needs.
Avoid trips and maximize steam output by reviewing your control equipment, strategy, and tuning.
A decision to leverage the relatively small cost of a quality scope and solid conceptual design can create significant long term savings and achieve an optimum solution.
Implementing lean manufacturing requires participants to review job environment and satisfaction, motivate participation, demand leadership responsibility, develop new behavior patterns, and insist on lean methods and tools.
Engineering and IT Insight: UML (Unified Modeling Language) is the language of software engineering, and State Models in UML are used to define internal logic. When state diagrams, use case diagrams, and sequence diagrams are combined with UML class diagrams they define a system, can be easily understood by non-programmers, and can be rapidly converted into executable code.
Automation Integrator Guide: Motion control and automation integration challenges reside where containers are stacked. Multiple automation container terminals operate and more are in development, presenting a grand-scale motion control opportunity.

How to select a VFD – These guidelines dispel the confusion about matching variable frequency drives (VFD) and motors to fans and pumps that are typically encountered in commercial building applications. While the motivation to increase energy efficiency could be financial (reduced energy costs) or ethical (reduce greenhouse gas emissions associated with power production), it is taken for granted that VFDs are an easy way to improve energy efficiency in a motor application. And with these noble intentions in mind, the engineer will specify a VFD for his client. Oftentimes, that isn’t the end of the story for the engineer.
Effective bonding, grounding: The backbone of electrical safety – Providing and maintaining an effective impedance path to ground is critical to maintain reliable, efficient, and safe operating facilities.
Disturbance-Rejection vs. Setpoint-Tracking Controllers – Designing a feedback control loop starts with understanding its objective as well as the process’s behavior.
When worlds collide – Does a meeting of the IT group and the controls group always have to result in a collision? Can we avoid the broken glass?
