Set point theory can be construed as implying weight regulation in a wide or tight range around the set point, in a symmetric or in an asymmetric manner (i.e. treating weight gain and loss either the same or differently), and may apply to regulation of body fat levels specifically (in a multi-compartment model) or to overall body weight. Set ...
Set point (endocrinology), a term encompassing a number of quantities (e.g. body weight, body temperature) where the endocrine system contributes to regulation and homeostasis. Setpoint (control system), the target value that an automatic control system, for example PID controller, will aim to reach; Set point theory, a theory describing how ...

An everyday example is the cruise control on a road vehicle; where external influences such as gradients cause speed changes (PV), and the driver also alters the desired set speed (SP). The automatic control algorithm restores the actual speed to the desired speed in the optimum way, without delay or overshoot, by altering the power output of ...
One of the effector organs is the heart whose rate is stimulated to rise (tachycardia) when the arterial blood pressure falls, or to slow down (bradycardia) when the pressure rises above the set point. [18] Thus the heart rate (for which there is no sensor in the body) is not homeostatically controlled but is one of the effector responses to ...
