Abstract
A control system for controlling a heater includes a power converter, a sensor circuit, and a controller. The power converter supplies an adjustable power to the heater, and the sensor circuit is configured to measure an electrical characteristic of the heater. The controller is coupled to the power converter to control the power to the heater, and is configured to select a state model control, as an operation state of the heater, from among a plurality of defined state model controls. The controller controls the power supplied to the heater based on the operation state of the heater and on the electrical characteristics of the heater.
