数控机床热误差补偿高次多阶ADL模型应用分析
Application of High Order and Multi-level Autoregressive Distributed Lag Model to Thermal Error Compensation of Machine Tools
摘要
Abstract
Based on the synthesis of the fuzzy clustering and gray relational theory,the temperature sensors for monitoring CNC machine tools were optimized.According to the commonly used multiple regression model,this paper used ADL model to model the thermal error of CNC machine tools.On the basis of better accuracy,we expanded the ADL model and proposed a new high order and multi-level ADL modeling technique,also,analysed its modeling method and accuracy.It shows that the high order and multi-level ADL model has better accuracy in the thermal error compensation of CNC machine tools by the examples presented herein.关键词
