Block diagram of a negative feedback system used to maintain a setpoint in the face of a disturbance using error-controlled regulation. Positive error means feedback is too small (controller calls for an increase), and negative error means feedback is too large (controller calls for a decrease).

In cybernetics and control theory, a setpoint (also set point, set-point) is the desired or target value for an essential variable of a system,[1] often used to describe a standard configuration or norm for the system.[2] Departure of a variable from its setpoint is one basis for error-controlled regulation,[3] that is, the use of feedback to return the system to its norm, as in homeostasis. For example, a boiler might have a temperature setpoint, which is the temperature the boiler control system aims to maintain.
