Equipped with flow regulator in system, electro-hydraulic proportional speed regulating valve can decrease leveling time in high speed gear, and ensure leveling accuracy in low speed gear.
系统中设有流量调节环节，电液比例调速阀在快挡可以缩短整个调平时间，在慢挡可以保证调平精度。
Because nonlinear parameters such as long-pipe, valve-controlled asymmetrical cylinder and load disturbance had impact on leveling system of aerial platform.
阀控非对称缸系统存在着大量的非线性和不确定因素，这些因素对系统稳定性的影响非常复杂。
