在农作物金银花干燥期间,为了满足干燥热风的温度和风速的稳定性要求,针对热风炉出风口热风温度与设定的温度值滞后和稳定性差等问题,设计了一套以单片机STM32作为核心处理器和模糊自适PID算法作为参数控制器的控制系统,实现模糊自适PID算法对参数进行调整。利用Matlab语言建立模型,对整套控制系统进行仿真分析。结果表明:出风口热风温度的稳定性能达到95%以上,该研究方法提高控制系统的性能,有利于农作物干燥的质量和效率。

The study aims to satisfy the stability requirement of dry hot air temperature and wind speed duringthe dry period of the crop honeysuckle.To solve the problems of inaccurate air temperature setting andinstability of the outlet air temperature of the hot air stove,a control system based on STM32 as the coreprocessor and the fuzzy adaptive PID algorithm is designed,and the parameters are adjusted by the fuzzyadaptive PID algorithm.Using Matlab language to build the model,simulation analysis of the whole controlsystem is conducted,the results show that the stability of the outlet air temperature...
