【摘要】 建立了二次调节静液传动位置系统的数学模型，并在允许的情况下将其简化为三阶系统．对位置闭环控制系统采用了模糊控制方法．并采取了在小转角时只控制转角，在大转角时同时控制转角和转速的控制策略．经试验研究表明，采用模糊控制能取得较好的控制效果，而这种转角—转速控制策略符合理想的位置控制过程．更多还原

【Abstract】 A mathematical model is built for the hydrostatic drive position system with secondary regulation in accordance with its actual operatine conditions and it is simplified as appropriate into a third order model. Fuzzy control method is then applied to the model without speed control while the revolution is small, with both revolution androtation speed controlled while the revolution is large, experimental results prove better control can be achieved withfozzy control and the angle of rotation and rotation speed control method is in line with ideal position control.更多还原
