二次调节转速系统的双闭环控制研究

Research on double closed - loop control system of hydrostatic transmission with secondary regulation

本文建立了二次凋节静液传动系统双闭环控制的数学模型，对系统进行了单、双闭环控制的对比研究。理论分析与试验结果表明：双闭环控制由于提高了系统的阻尼比因而较之单闭环控制具有更好的控制特性。

In this paper, double closed - loop mathematical model of hydrostatic transmission system with secondary regulation is established. A contrast study is carried out on single and double close - loop control systems. Theoretical analysis and experimental results show that better control results can be achieved with double closed - loop control system than single one due to improving the damping ratio of the system.
