Classification: CPC G  H | IPC G  H

Claim 0:
1. A method for controlling a heated process of a heater, the method comprising:
obtaining a first setpoint variable indicating a first target temperature of the heater;
identifying an energy profile for the heater based on the first setpoint variable, wherein the energy profile provides a defined magnitude of initial electrical energy to be applied to the heater to have a temperature of the heated process reach the first target temperature; and
providing first electrical energy to the heater based on the energy profile, wherein the energy profile is based on:
obtaining a second setpoint variable indicating a second target temperature of the heater;
providing second electrical energy to the heater, wherein the second electrical energy has a calibration magnitude;
obtaining 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 of the heater or the second target temperature of the heater:
determining a response time of the heater;
selectively adjusting gain values of a controller based on the response time; and
generating the energy profile based on the gain values and the first setpoint variable or the gain values and the 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.
