What is the difference between the control, dependent variable, and independent variable in a scientific experiment?|||The "experiment" you allude to must be a closed-loop control system, for those terms to be applicable.
The independent variable is the input to the control system, basically, a setpoint change, or a load change, aka, disturbance.
The dependent variable is any output of the control system, i.e. flow, temperature, pressure, level, etc.
The control variable is the dependent variable right after the controller, into the control element, ie, flow control valve, heater, etc.
