Hello everyone,

Lately, I have been encountering frequent issues with the stability of the MALM processes, especially during longer runtimes and varying load conditions. My question is: How can the stability of MALM be improved on a lasting basis, particularly concerning dynamic system parameters and different environmental conditions?

I am especially interested in which specific adjustments in control engineering, filtering, or data processing are truly durable and reliable. Are there any proven best practices or newer methods that have already been successfully applied in professional use?

Thanks in advance for your tips and experiences!

In addition to software optimization, I recommend regularly checking sensors and actuators and calibrating them if necessary. Faulty or drifting measurements are common causes of instabilities.

An additional way to improve the long-term stability of Malm is the implementation of a systematic early fault detection system.

Using machine learning, deviations from the normal condition can be detected early, and countermeasures can be initiated automatically.

This complements traditional control methods and significantly increases reliability. Documenting the fault history also aids in continuous optimization.

The approach of machine learning is proving to be increasingly efficient:

It is advisable to rely on supervised learning methods with a large, validated dataset to minimize false alarms. At the same time, the implementation should be modular and designed for compatibility with existing control systems.

Important: Consistently analyze logs instead of just collecting them. This is the only way to identify patterns for problems early on.

In conclusion, the long-term improvement of MALM stability is mainly achieved through a combination of adaptive control, regular maintenance, sensor monitoring, and modern fault detection.

Expanding the data base is therefore key to sustainable improvements.
