When the second running time accumulates to 100 ms from zero, the second running time reaches the second time mark; before the second running time reaches 100 ms, the second running time does not reach the second time mark.

[0056] Secondly, the second time mark is preferably 100 ms, and the second running time is recorded in a progressive manner, i.e. the second running time starts from zero and increases to 100 ms. When the second running time accumulates to 100 ms from zero, the second running time reaches the second time mark; before the second running time reaches 100 ms, the second running time does not reach the second time mark.

[0057] S322, if the second running time does not reach the second time mark, updating the rotating position S of the servo motor every second set time i , and returning to step S321, wherein the second set time is greater than the first time.

[0058] Specifically, the second set time is 5-20 ms, preferably 10 ms. Before the second running time reaches 100 ms, or before the second running time decreases from 100 ms to zero, the rotating position S of the servo motor is updated every 10 ms according to the formula , and so on. When the second running time reaches the second time mark, the rotating position S of the servo motor is updated 10 times cumulatively i by the stove, so that the firepower is adaptively updated according to the level of the gear knob. i

[0060] S323, if the second running time reaches the second time mark, clearing the second running time and returning to step S2.

[0061] Specifically, when the second running time reaches the second time mark, the second running time is cleared, if the second running time is recorded in a progressive manner, the second running time is reset to 0 ms; if the second running time is recorded in a decreasing manner, the second running time is reset to 100 ms.
