The top 5 most read articles online, from Aug. 30 to Sept. 5, 2021, for Control Engineering covered APC improvements, industrial products, face mask prototypes, industrial products, control system improvements and jumpstarting a successful IIoT program. Links to each article below.

1. Understanding the matrix for APC improvements

More agile tools are helping multivariable control become more effective for advanced process control and other applications than traditional model-based control (MPC) and real-time optimization. Process engineers, operations personnel, DCS and APC engineers, and other process operation and optimization stakeholders benefit from understanding the matrix.

2. Rethinking the way industrial products are purchased

Greater operational efficiency is required in manufacturing today and it requires a comprehensive look at everything, starting with how things are purchased. See four clarifications on consolidated industrial purchasing advantages.

3. Face mask prototype can detect COVID-19 infection

Engineers at MIT and Harvard have designed a prototype face mask that can diagnose the person wearing the mask with COVID-19 within about 90 minutes and can be used to detect other pathogens and chemicals.

4. Control system improvements: Feed-forward, adaptive, fuzzy control

Control methods that can be more effective than proportional-integral-derivative (PID) controllers, include feed-forward control, disturbance compensation, adaptive control, optimal PID control and fuzzy control.

5. Five steps for jumpstarting a successful IIoT program

The Industrial Internet of Things (IIoT) and condition-based maintenance (CBM) alter the way we identify, assign and complete work.

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, Aug. 30 to Sept. 5, 2021, for articles published within the last two months.
