Hot topics in Control Engineering, for April 2021, included control loop tuning, control system evolution, Engineers’ Choice winners, COVID-19 refining tests and SCADA master plans. Links to each article below.

1. Know where to start with control loop tuning

Understanding proportional gain and integral time’s functions in control loop tuning values and how they work together is important.

2. Evolution of control systems with artificial intelligence

Cover Story: Can artificial intelligence (AI) prove to be the next evolution of control systems? See three AI controller characteristics and three applications.

3. Spotlight on Innovation: 2021 Engineers’ Choice Awards

Control Engineering announces the best automation, control and instrumentation products in the 21 categories of the annual Engineers’ Choice Awards program.

4. Refining tests for detecting COVID-19 in wastewater facilities

Rice University-led study evaluates methods to find signs of COVID-19 virus in municipal wastewater plants and have found a viable and consistent method for detection.

5. Developing a SCADA master plan framework

The best application of the supervisory control and data acquisition system’s components ensure the continuity of a water and wastewater plant’s operational success.

6. How to accelerate data visualization

As the volume of industrial data grows exponentially, human-machine interfaces (HMIs) are providing improved data visualization and storytelling tools to support intelligent automation and strategic decision making.

7. Edge computing provided cost-effective upgrades

Case study: Used equipment had functional controllers, typically legacy programmable logic controllers (PLCs), and others had defunct PLCs or no automation at all. Edge controllers and input/output (I/O) devices helped integrate the equipment into a cohesive system, which led us to make an edge controller the central focus.

8. Tools troubleshoot industrial Ethernet problems

Technology ranges from the simple to the sophisticated.

9. Practical and value-based Industry 4.0

Industry 4.0 might seem daunting and expensive, but manufacturers can make it practical without getting bogged down in details.

10. Let IIoT do the dirty work: automating sewage treatment

Sewage treatment case study tracks early success, including accuracy and reliability.
