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．
A mathematical model for the secondary regulation of the hydrostatic drive position system was established and reduced to a third-order system, if allowed. Closed loop control system uses a fuzzy control method. And took only control the corner when the small corner, at the same time control the corner and speed control strategy. The experimental study shows that the fuzzy control can achieve better control effect, and this corner - speed control strategy in line with the ideal position control process.
