摘　　要：为提高马弗炉的温度控制精度和稳定性,针对工业加热炉温控需求,开发了一款基于STM32单片机的温度控制器。通过精密的温度传感器采集炉内及样品室的温度数据,并利用模拟数字信号转换器将所采集的模拟信号转换为数字信号,传输至STM32单片机进行处理。温度的调节通过可控硅调压技术实现,以精确控制加热功率。采用MATLAB软件建立数学模型,并基于此模型确定了最优PID控制策略。实验结果表明,相较于传统的单回路PID控制,采用串级PID控制策略能显著提高温度控制的精度和稳定性,证明了所设计控制器在实现马弗炉精确温控方面的有效性和优越性。不仅明显提升了马弗炉的温度控制性能,也为类似的工业温度控制应用提供了可靠的技术方案,展示了明显的创新性和应用价值。此项研究成果对于推动高精度、高稳定性温度控制技术在工业领域的应用具有重要意义。To improve the precision and stability of the temperature control in muffle furnaces,a temperature controller based on STM32 microcontroller has been developed to meet the temperature control requirements of industrial heating furnaces.The temperature data inside the furnace and sample room are collected by precision temperature sensors,and the collected analog signals are converted into digital signals by an analog-to-digital signal converter,which are then transmitted to the STM32 microcontroller for processing.The temperature adjustment is achieved through thyristor voltage regulation technology to accurately control the heating power.A mathematical model is established using MATLAB software,and the optimal PID control strategy is determined based on this model.The experimental results show that compared to traditional single loop PID control,the use of cascade PID control strategy can significantly improve the accuracy and stability of temperature control,proving the effectiveness and superiority of the designed controller in achieving precise temperature control of muffle furnaces.It not only significantly improves the temperature control performance of muffle furnaces,but also provides reliable technical solutions for similar industrial temperature control applications,demonstrating obvious innovation and application value.This research achievement is of great significance for promoting the application of high-precision and high stability temperature control technology in the industrial field.
