【摘要】：為了抑制壓力波動,對完整飛行剖面下的液壓系統(tǒng)工作狀態(tài)進行分析.針對飛機液壓系統(tǒng)提出流量負載模擬器原理,設(shè)計新型變速積分PI控制器,建立系統(tǒng)數(shù)學模型,確定各參數(shù)取值,開展數(shù)值仿真和試驗研究,指出該流量負載模擬器的優(yōu)缺點.仿真和試驗結(jié)果均表明,在完整飛行剖面下,液壓系統(tǒng)的可用壓力在20.4 MPa以上,液壓系統(tǒng)穩(wěn)定可靠.相比于增量式PI控制器,采用變速積分PI控制器的壓力波動至少減小了40%.
[Abstract]:In order to restrain the pressure fluctuation, the working state of the hydraulic system under the complete flight profile is analyzed. According to the principle of flow load simulator for aircraft hydraulic system, a new type of variable speed integral PI controller is designed, the mathematical model of the system is established, the values of each parameter are determined, the numerical simulation and experimental research are carried out, and the advantages and disadvantages of the flow load simulator are pointed out. The simulation and test results show that the available pressure of the hydraulic system is above 20.4 MPa under the complete flight profile, and the hydraulic system is stable and reliable. Compared with the incremental PI controller, the pressure fluctuation of the variable speed integral PI controller is reduced by at least 40%.
