To calculate flow rate of valve in the throttled position , multiply the flow rate from step 6 . 3 . 4 by the percentage flow rate from step 6 . 3 . 2 divided by 100 為了計算處于節(jié)流位置的閥門的流量,將從步驟6 . 3 . 4得到的流量乘以叢步驟6 . 3 . 2得到的百分比流量,再除以100 。
Then pid flow rate control algorithm is introduced . all experiments made in this chapter are about measuring the valve parameters according to spool positions , single actuator flow rate control by the calculated flow rate feedback control method , free flow rate dividing control under the sufficient pump discharge flow rate situation , proportion flow rate dividing and flow rate dividing based on meter - in flow rate feedback control method under insufficient pump discharge flow rate situation . the results of all experiments proved that the method presented in this thesis is an effective way to overcome the unreasonable flow rate dividing when simultaneously operating multi - actuators with different inertia loads 第四章介紹了多執(zhí)行器復合控制實驗系統(tǒng)和實驗方法;介紹了實驗采用的流量控制的pid算法;并測定了執(zhí)行器控制閥和閥芯位移相關的系數(shù);做了單個執(zhí)行器計算流量反饋流量控制、流量足夠情況下多執(zhí)行器流量任意分配、流量不足情況下多執(zhí)行器按比例調節(jié)流量分配和多執(zhí)行器進油側流量反饋分流控制實驗;通過實驗說明了論文提出的分流控制方法能實現(xiàn)大小慣性負載復合操作時的合理分流。
