säädinpiiri
A säädinpiiri, also known as a control loop or regulator circuit, is a fundamental concept in automation and control systems. It is an electronic circuit designed to maintain a desired output quantity at a specific setpoint, despite variations in the input or external disturbances. The primary function of a säädinpiiri is to continuously monitor the output, compare it to the target value, and adjust a control signal to minimize any difference or error.
The basic components of a säädinpiiri include a sensor, a comparator, a controller, and an actuator. The
Säädinpiirit can be broadly classified into two main types: open-loop and closed-loop. In an open-loop system,
