The top 5 most read articles online, from April 15-21 for Control Engineering covered rate-predictive control, the Engineers’ Choice Awards, feedforward control, temperature sensor calibration, and connecting quality and process data. Links to each article below.

1. What is rate-predictive control?

Advanced control: A new non-PID control algorithm, rate-predictive control (RPC), is adaptive to changes in process gain, which is helpful given the industry’s difficult history of loop tuning, auto-tuning, and model maintenance. RPC also can serve as a model-less feedback multivariable control algorithm.

2. 2019 Engineers’ Choice Awards

Spotlight on innovation: Best automation, control, and instrumentation products in 26 categories.

3. Understanding feedforward control

Feedforward controls applied to a process, with limited, measurable disturbances, can keep the process variable close to the setpoint.

4. Temperature sensor calibration

Sensor failure risks are significantly reduced if the temperature sensor can be calibrated in situ.

5. Connecting quality data to process data

Using advanced analytics can help assure product quality and overall operational efficiencies. See case study example.

The list was developed using CFE Media’s web analytics for stories viewed on, April 15-21, for articles published within the last two months.
