sekundærkontroll

Sekundærkontroll refers to a type of control system where the primary function is to regulate a process based on a secondary parameter or condition. Unlike primary control systems that directly manage a main variable like temperature or pressure, secondary control systems intervene or adjust the primary control when a specific secondary condition is met. This is often employed to optimize efficiency, ensure safety, or maintain a desired state beyond the immediate process variable.

For instance, in a heating system, the primary control might regulate the room temperature. A secondary control could be activated if the humidity in the room exceeds a certain threshold. This secondary control might then adjust the heating system's operation, perhaps by increasing airflow or temporarily reducing the heat output to facilitate dehumidification, even if the temperature is still within the desired range.

Another example can be found in manufacturing. A primary control might govern the speed of a conveyor belt. A secondary control could monitor the weight of items on the belt and, if the weight exceeds a predefined limit, signal a different part of the system to slow down or stop the belt to prevent damage or overload. The secondary control, in this case, acts as a safeguard or an optimization layer over the primary process.

The implementation of sekundærkontroll requires careful design to ensure it complements, rather than conflicts with, the primary control. It often involves sensors for the secondary parameter and logic that dictates when and how the secondary control should influence the primary system or other related systems. The goal is to achieve a more nuanced and robust overall control strategy.
