The invention belongs to the technical field of induction
cooker power intelligent adjustment, and particularly relates to an induction
cooker intelligent power adjustment method and
system based on cookware impedance identification, and the
system comprises a
signal generation and collection module, an
impedance spectrum analysis module, a temperature collection module, a cookware identification module, a main control module and a response driving module. The method comprises the following steps: in a cookware detection stage, outputting a micro-
power test signal with gradually varied frequency and constructing an impedance-
frequency curve according to the micro-
power test signal; performing dynamic temperature compensation on the impedance parameter; identifying the type of the cookware, and querying a power mapping
database to obtain an optimal
power control strategy; in the heating process, the impedance change trend is predicted; and synthesizing the real-
time deviation and the predicted deviation, calculating a
power regulation instruction, and driving an
inverter circuit to work. According to the induction
cooker, accurate identification of the cookware is realized, and the universality, safety, energy efficiency and cooking effect of the induction cooker are remarkably improved due to optimal power matching of the cookware and advanced smooth
intelligent control.
