The "eyes" of the system that measure variables like temperature, speed, or pressure.
James Watt's centrifugal governor (1788) was a major milestone, used to control the speed of steam engines automatically. Mathematical Tools Otomatik Kontrol
Engineering students typically study this using complex math to ensure a system is "stable" (meaning it doesn't spiral out of control). Key tools include: The "eyes" of the system that measure variables
