摘要:
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的水肥装置Smith控制系统(Smith PSO-Fuzzy PID)。并以目标EC值2mS/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。仿真结果表明:采用Smith PSO-Fuzzy PID控制方法,稳态时间约为47s,超调量约为4.83%,系统EC值稳定在1.987mS/cm~2.080mS/cm,与传统PID和Fuzzy PID相比,具有更快的响应速度,更高的精度。

Abstract:
In this paper, a multi-channel water and fertilizer integrated device is designed, which is composed of seven parts: industrial aluminum profile frame, main pipeline system, fertilizer suction system, fertilizer mixing system, detection system, control system and fertilizer application system. Smith control system of water and fertilizer device (Smith PSO-Fuzzy PID). Taking the target EC value of 2mS/cm as an example, the traditional PID, fuzzy PID (Fuzzy PID) and Smith PSO-Fuzzy PID simulations were carried out by MATLAB. The simulation results show that: using the Smith PSO-Fuzzy PID control method, the steady-state time is about 47s, the overshoot is about 4.83%, and the system EC value is stable at 1.987mS/cm-2.080mS/cm, which is comparable to traditional PID and Fuzzy PID. than, with faster response speed and higher precision.
