In an '''open-loop controller''', also called a '''non-feedback controller''', the control action from the controller is independent of the "process output", which is the process variable that is being controlled.<ref>"Feedback and control systems" - JJ Di Steffano, AR Stubberud, IJ Williams. Schaums outline series, McGraw-Hill 1967</ref>

It does not use [[feedback]] to determine if its output has achieved the desired goal of the input or process "set point". An open-loop system cannot engage in [[machine learning]] and also cannot correct any errors that it could make. It will not compensate for disturbances in the process being controlled.
