Abstract
A heating system includes a power supply that applies a first voltage to a sense resistor in series with a resistive heating material during a first time period; and a controller that determines a temperature of the resistive heating material based on a current through the sense resistor and a second voltage across the resistive heating material during the first time period. Additionally, the controller commands the power supply to provide a third voltage to the resistive heating material during a second time period, and the third voltage is based on the temperature of the resistive heating material.
