摘要
以位置全闭环控制策略的数控机床伺服进给系统为研究平台,研究伺服放大器中霍尔电流传感器、编码器与光栅尺等无传感器测试原理,探索无传感器信息与故障的关联性以及无传感器信息用于故障评估的可行性;并且针对不同类型的数控系统,提出不同的数据采集方法。为数控机床伺服进给系统在线性能评估奠定了基础。
Based on the research platform of position-closed-loop servo control system of servo driving system of numerical control （NC）machine tool,the testing principles of sensor-less of Hall current sensor in servo amplifier,encoder and grating scale were re-searched,and the feasibility of information of sensor-less used in faults evaluation and relationship between faults and information of sensor-less were explored. Besides,different data sampling methods were presented by aiming at different NC systems. It is the base of performance evaluation of servo driving system of NC machine tool on-line.
