We consider coherent feedback control of quantum transport and focus on the application of simplecontrollers and the effects of a finite bias voltage. We show that simple single-parameter controllerscan give rise to a range of useful effects such as amplification of changes in plant transmission,increased resolution of energy filtration, and the detection of differences between otherwiseindistinguishable plants. We explore how these effects are impacted by the phase-averaging effectsassociated with finite bias and identify important voltage scales for the maintenance of thefunctionalities achieved through feedback control.
