摘　　要：文章利用模糊智能控制与PID算法结合而成的模糊PID算法实现对水温控制效果的优化,采用STM32F103RCT6单片机作为主控芯片完成算法机器化,DS18B20温度传感器实现对温度的实时检测,光耦继电器作为控制媒介完成对水温的控制。结果表明利用模糊PID算法进行水温控制可以明显提升控制对象的稳定性,较好地解决传统水温控制过程中存在的超调问题,并且抗干扰性有显著提升。该设计还可推广至其它控制领域,对模糊控制实践化有一定的价值。In this paper,fuzzy PID algorithm combining fuzzy intelligent control and PID algorithm is used to optimize the control effect of water temperature.STM32F103RCT6 MCU is used as the main control chip to complete the algorithm of automatization,DS18B20 temperature sensor to achieve real-time temperature detection,photocoupling relay as the control medium to complete the control of water temperature.The results show that using fuzzy PID algorithm to control water temperature can obviously improve the stability of the control object,better solve the problem of overshoot in the process of traditional water temperature control,and significantly improve the anti-interference.This design can also be extended to other control fields,and has certain value for fuzzy control practice.
