基于模糊PID控制的商用电磁炉控制系统设计

摘要

本文根据商用电磁炉工作原理和设计要求,在硬件方面以STC12C5410AD单片机作为系统的主控制芯片设计了主电路.在软件方面,主要采用模糊PID复合控制,并结合PWM和PFM两种调功方式.实验证明,这种设计减少了电磁炉工作时的电磁污染与电能浪费,符合节能减排的政策导向.%According to the working principle and design requirements of commercial induction cooker, the main circuit is designed on the hardware side with STC12C5410AD microcontroller as the main control chip of the system. In software, the main use of fuzzy PID composite control, combined with PWM and PFM two kinds of power regulation. Experiments show that the design reduces electromagnetic pollution and electrical energy waste in the work of the electromagnetic furnace, and is in line with the policy guidance of energy saving and emission reduction.
