摘　　要：本文以二次调节系统中液压马达的输出扭矩为控制对象进行了实验研究．首先在恒压网络中实现恒排量控制，完成恒扭矩调节的最初模型．在这一基础上引入压力反馈信号，实现对扭矩更为精确的控制。This paper regards hydraulic motor's torque as controling object with experimental investigation,in the first,constant displacement control is accomplished in constant presure network,then the primary model of constant torque control is brought out.On the basis of this study,pressure single is brought go as to make a compensation.So that more precise torque control than constant displacement control is accomplished,this means the error that load varing makes is removed.

关 键 词：液压系统 二次调节 恒扭矩
