# Knowledge about process control, without the noise.

> Articles on process control and process optimisation in plain language. From the basics of PID controllers to recognising unrest in your own trends.

- [How do control loops perform in practice? What the research says](/en/knowledge/control-loop-performance.md) (2026-10-07): Research into hundreds of thousands of PID control loops keeps showing the same picture: a large share is in manual, oscillates or runs into a limit. The figures, the sources and the caveats.
- [Process control: the basics of industrial control engineering](/en/knowledge/process-control.md) (2026-09-19): How does process control work in the process industry? Learn how feedback, feedforward and process dynamics come together in stable, well-performing control.
- [PID controller explained: how it works, settings and process dynamics](/en/knowledge/pid-controller-explained.md) (2026-08-17): How does a PID controller work? Learn what P, I and D do, how process dynamics determine the right settings and how to recognise control behaviour in trend data.
