The invention discloses a hydraulic circuit. The hydraulic circuit may include a hydrostatic pump providing fluid to a hydraulic motor at a flow rate, where the hydrostatic pump has a displacement, and where the hydraulic motor drives a swing element; the swing loop pressure sensor is used for sensing the loop pressure of the hydraulic loop; a pilot pressure actuator that controls a displacement of the hydrostatic pump based on a supply pressure; a pilot pressure override valve for controlling the supply pressure; and a controller configured to adjust the supply pressure based on the sensed signal and with the pilot pressure override valve, where the sensed signal includes: a loop pressure signal based on the loop pressure sensed by the swing loop pressure sensor; and a sensed swing speed signal, the sensed swing speed signal based on a swing speed of the swing element sensed by the one or more machine sensors. 本发明公开了一种液压回路。所述液压回路可包括静液压泵，所述静液压泵以一定流速将流体提供到液压电机，其中所述静液压泵具有排量，并且其中所述液压电机驱动摆动元件；用于感测所述液压回路的回路压力的摆动回路
