Figure 3: Here the block diagram from figure 2 has been rearranged into a more familiar configuration that is functionally identical to a traditional feedback controller (blue) equipped with a setpoint filter (green) and a feedforward path (red). Most commercial feedback controllers include setpoint filtering and feedforward as standard options, making this version of model-following control simpler than the original version, and much easier to implement.

The top 5 most read articles online, from September 2-8 for Control Engineering covered model-following control, industrial controller cybersecurity, machine learning, improving engineer retention, and IIoT platforms. Links to each article below.

1. The basics of model-following control

Two proportional-integral-derivative (PID) controllers can be better than one. Model-following control may be the best choice if it’s important to get the process variable to the setpoint without hunting or overshoot.

2. Industrial controller cybersecurity best practices

Protecting industrial automation systems is easier when controllers offer built-in cybersecurity features.

3. Machine learning used to determine warehouse ergonomics for worker safety

Researchers at the University of Washington used machine learning to develop a system that monitors factory and warehouse workers and tell them, in real time, how risky their behaviors are.

4. Three ways to improve engineer retention

Companies looking to protect their top engineering talent from rivals should look to improve training, benefits and wages to make employees happier and more productive.

5. Not all IIoT platforms are created equal

Having the best Industrial Internet of Things (IIoT) architecture with the most modern and state-of-the-art technology will not benefit any company unless it is tied to a specific purpose and business outcome.

The list was developed using CFE Media’s web analytics for stories viewed on, Sept. 2-8, for articles published within the last two months.
