In accordance with embodiments of the present disclosure, a system may include a controller configured to control a process value using closed-loop control, wherein: (i) when using closed-loop control, the controller controls the process value based on a measured process value indicative of the process value communicated from a sensor and by generating a driving signal that is a maximum of a first driving signal which is the function of the measured process value and a second driving signal; and (ii) the controller is configured to disable polling by the controller of the sensor for the measured process value when the driving signal is greater than a threshold open-loop driving signal sufficient to maintain the process value within a desired range of the process value in the absence of closed-loop control.
