【目的】探寻多通道水肥控制装置的精准调控与控制技术。【方法】本文设计了由工业铝型材机架、主管路系统、吸肥系统、混肥系统、检测系统、控制系统及施肥系统等7部分构成的多通道水肥一体化装置，构建了基于PSO优化Fuzzy PID的营养液EC值调控模型并引入Smith预估当中（Smith PSO-Fuzzy PID）。并以目标EC值2 mS/cm为例，采用MATLAB分别进行了传统PID、模糊PID（Fuzzy PID）和Smith PSO-Fuzzy PID仿真。【结果】采用Smith PSO-Fuzzy PID控制方法，稳态时间约为47 s，超调量约为4.83%，系统EC值稳定在1.987~2.080 mS/cm。【结论】与传统PID和Fuzzy PID相比，本文基于PSO优化Fuzzy PID...
