数字式变量泵的控制性能研究

摘要

Introduced a new digital variable pump and it's working principle,through the AMEsim software and establishment of its mathematical model,researched its characteristics of control performance,and different parameters on their performance.Analysis showed that the response time and the pressure fluctuation range of the digital variable pump were affected by the pre-pressure of the accumulator and the PWM control signal.%介绍了一种新型的数字式变量泵及其工作原理.通过建立其数学模型和AMEsim仿真软件,研究其控制性能特性,分析不同参数对其性能的影响.分析结果显示,蓄能器预压力和PWM控制信号频率,对数字式变量泵的响应时间和压力波动范围有着重要的影响.
