介绍一种超高温液压泵源方案及电液比例控制系统的死区动态补偿

draulic proportional control systems

本文提出一种液压隔离式的新型泵源方案来做超高温泵源。针对泵源使用的比例换向阀的死区特性 ,提出了一种死区自学习动态补偿方法。实验表明 ,这种动态补偿方法在比例换向阀对响应速度和精度有较高要求时 ,取得了满意的结果 。

This paper puts forward a novel hydraulic isolation pump to act as super high temperaturepump. And a self - study dynamic compensation method is advanced to solve the deadzone speciality of theproportional valve used in this novel pump. The result has approved that this real time method is effective. whenhigh precision and speed are needed.\;
