With the color IH Fusing system, placing a coil that generates a high-frequency magnetic field inside a metallic sleeve results in an eddy current, heating the sleeve itself. The IH sleeve, with its thin metallic film, heats up very rapidly. Using conventional heat-control methods, this could lead to significant overshooting or undershooting of the target temperature. To resolve this problem, Canon developed a low-loss, high-frequency inverter that controls output in the wide range of 20 kilohertz (kHz) to 50 kHz. By adjusting the frequency, its output power is controlled around a full 1 kilowatt (kW) during ramp up, whereas it is kept minimum to keep the target temperature after warm up, achieving extremely stable temperature control with almost no temperature deviation, despite the low heat capacity of the IH sleeve.

Fuzzy control in its basic form mimics a man ual control process. A person regulates power applied to a heating element according to the momentary temperature deviation from the setpoint value (the regulation error, e(n)) and the rate of the temperature change (or derivative of the regulation error, (e(n)). The entire process is governed more by a sense than by the knowledge of its physical or mathematical behavior. Are the temperature deviation and the rate of the temperature change high, low, or medium? Fuzzy control works exactly with the same states of the process variables.

Acceptable temperature deviation from set point is plus or minus 2ΊF
