【摘要】 介绍了液压恒压网络的结构组成,建立了液压变压器-液压蓄能器子系统的数学模型,提出了两种分别依赖于负载流量和系统压力的压力控制算法。在分析前者的缺点后,推导了控制系统压力的非线性方程,该方程的解及其系统压力的仿真结果证实了所提出的第二种恒压网络的控制方法的正确性。更多还原

【Abstract】 Based on instruction of the structure of hydraulic net, the mathematical model of the subsystem with hydraulic transformer and accumulator in series is established. Then, two arithmetic to control the pressure of system according to load flow and the pressure of system respectively are put forward. After analyzed the shortcoming of the former, a nonlinear control equation is educed. The result of the control equation and simulation proves feasibility of the second control method.更多还原
