Säätökohteet

Säätökohteet are a fundamental concept in control engineering, referring to the specific physical quantities or variables within a system that are intended to be regulated or manipulated. These are the parameters that a control system aims to keep at a desired setpoint or to change according to a predefined profile. For instance, in a heating system, the temperature of a room is a säätökohde. The control system measures the current temperature and adjusts the heating elements to maintain the desired temperature. Other common examples include the speed of a motor, the flow rate of a liquid, the position of a robotic arm, or the voltage of a power supply.

The choice of säätökohde is critical for the effective design and operation of any control system. It must be a variable that can be reliably measured by sensors and influenced by actuators. The performance of the control system is directly judged by how well it can control its designated säätökohde, minimizing deviations from the setpoint and responding appropriately to disturbances. Understanding the characteristics and dynamics of each säätökohde is essential for selecting appropriate control strategies and tuning control parameters. In complex systems, there might be multiple säätökohteet, each requiring its own control loop or integrated into a multi-variable control scheme.
