suhdenhallinta
suhdenhallinta, literally translated as “ratio control,” is a principle used in electrical and mechanical engineering to adjust the proportional aspect of a system’s response. The concept emerged in the early 20th century alongside the development of feedback control theory and was later applied to industrial process control and power electronics. In practical terms, suhdenhallinta involves the tuning of a control coefficient—often called the proportional gain—that determines how aggressively a system reacts to deviations from a set‑point.
In modern technology, suhdenhallinta is implemented in both analog and digital controllers. Analog implementations use resistive
The technique is closely related to proportional–integral–derivative (PID) control, though suhdenhallinta focuses solely on the proportional
In Finland, the term has been adopted in academic curricula and industry standards, particularly within electrical
