CLOSED-LOOP CONTROL OF SWING

A system (118) and method for controlling the swing of a machine (100) is disclosed. The system (118) may comprise a hydrostatic circuit (120) that includes an electronic displacement control pump (122) and a first swing motor (124a) fluidly connected in a closed loop circuit. The electronic displacement control pump (122) configured to control the supply of fluid to the swing motor (124a) based on a final pump displacement command. The first swing motor (124a) configured to rotate the upper carriage (104) of the machine (100). The hydrostatic circuit (120) configured to control (a) an actualspeed of the first swing motor (124a) when the final pump displacement command results from a requested swing motor speed and (b) a torque of the first swing motor (124a) when the final pump displacement command results from a requested swing motor torque. 本发明公开了用于控制机器(100)的摆动的系统(118)和方法。所述系统(118)可以包括静压回路(120)，所述静压回路包括电子排量控制泵(122)和流体连接在闭环回路中的第摆动电机(124a)。所述电子排量控制泵(122)被配置成基于最终泵排量命令控制流体向第摆动电机(124a)的供应。所述第摆动电机(124a)被配置成使所述机器
