摘要
直线伺服系统是数控机床中的重要组成部分,其性能优劣直接决定和影响数控装置的快速性、稳定性及精确性。采用直线电机构成的伺服系统可以实现电机与工作台之间的零传动,具有响应速度快、效率高和位置跟踪准确的特点。本文以永磁直线同步电机作为执行器,根据空间矢量解耦控制思想,建立位置比例调节及速度IP调节下的直线伺服控制结构,并以此为背景对迭代学习控制方法开展研究,以实现系统良好的位置跟踪能力及鲁棒性能。
Linear servo system is an important constituent of numerical control machine tool. The advantages and disad- vantages of linear servo system performance can directly decide and affect rapidity, stability and accuracy of numerical control device. The servo system made up of linear motor realizes zero transmission between motor and worktable with merits of fast response, high efficiency and position tracking precision. According to the idea of space vector decoupling control, this thesis establish the permanent magnet linear synchronous motor servo control structure based on position proportion adjustment and speed IP adjustment. This thesis focuses on iterative learning control method of permanent magnet linear synchronous motor servo system. The purpose of the research is to realize satisfactory position tracking a- bility and robust performance of linear servo system.
