| 摘 要： | 采用小型针阀、直流电动机及减速器设计了机电流量控制阀，解决了变量喷雾过程中药液微小流量的控制问题。构建了机电流量控制阀传递函数的数学模型，并为之设计了模糊控制算法。对该流量控制阀进行了模糊控制和PID控制的MATLAB仿真，结果表明：模糊控制在响应速度和超调量方面优于PID控制，稳态误差两者均在±3.0%以内。

| Abstract: | To solve the control problem of micro-flow or low flow on pesticide in the course of variable rate spraying, an electromechanical flow control valve was developed with a miniature pin valve, a direct current(DC) motor, and gearset. A mathematical model of transfer function and arithmetic of fuzzy control were designed for the valve. The MATLAB simulation of the fuzzy controller and a PID controller was carried out on the electromechanical flow control valve. The results show that the fuzzy control is prior to PID control in the response speed and overshoot on this valve. Steady state errors are both within ±3%. |
