    摘要:

    構建了以電動調節(jié)閥為變流器件的變量噴霧系統(tǒng),，并采用試驗方法得出了系統(tǒng)的階躍響應特性，試驗結果表明：在階躍幅值ΔQ分別為0.4,、1.4,、3.4,、3.9、4.4L/min條件下，系統(tǒng)上升時間的最大值為1 s,，表明系統(tǒng)響應速度與現(xiàn)有的調壓變量噴霧系統(tǒng)相當；系統(tǒng)上升時間,、峰值時間和超調量都有幅值相關性,，說明系統(tǒng)是非線性系統(tǒng)。因此對此類調流變量噴霧系統(tǒng),，其控制設計必須考慮非線性問題,。

    Abstract:

    In order to develop a new type of precision spraying equipment, a set of variable-rate spray system based on electric control valve device as a converter was developed, and the step response characteristics of the system were studied by using experimental methods. The result shows that the maximum rise time is 1 s in the condition of step amplitude ΔQ=0.4, 1.4, 3.4, 3.9, 4.4L/min, which is comparable with variable-rate spray system controlled by changing flow press; the rise time, peak time and overshoot show correlation with the amplitude, which indicates that the system belongs to nonlinear system. So the control design of this type of variable-rate continuous spray system must take nonlinear problems into account.
