Classification: CPC G  H | IPC G  H

Claim 9:
10. A system for controlling a heater, the system comprising:
a non-transitory computer-readable medium; and
a processor configured to execute instructions stored in the non-transitory computer-readable medium, wherein an execution of the instructions cause the processor to:
obtain a temperature of the heater and one or more of a first target temperature of the heater or a second target temperature of the heater;
control the heater in an energy-based control mode based on the temperature and the one or more of the first target temperature of the heater or the second target temperature of the heater;
identify, during the energy-based control mode, an energy profile for the heater based on the one or more of the first target temperature of the heater or the second target temperature of the heater, wherein the energy profile provides a defined magnitude of initial electrical energy to be applied to the heater to have the temperature reach the one or more of the first target temperature of the heater or the second target temperature of the heater; and
provide, during the energy-based control mode, first electrical energy to the heater based on the energy profile, wherein the energy profile is based on instructions configured to cause:
obtainment of a setpoint variable indicating the second target temperature of the heater;
provision of second electrical energy to the heater, wherein the second electrical energy has a calibration magnitude;
obtainment of a first process variable indicating a temperature of the heater; and
when the first process variable indicates that the temperature of the heater is equal to the first target temperature or the second target temperature:
determination of a response time of the heater;
selective adjustment of gain values of a controller based on the response time; and
generation of the energy profile based on the gain values and a first setpoint variable or the gain values and a second setpoint variable, wherein the energy profile correlates the first setpoint variable to a first predetermined value of the first electrical energy or the energy profile correlates the second setpoint variable to a second predetermined value of the second electrical energy.
