摘要
高性能多坐标数控机床的摆头、转台等旋转进给系统多采用永磁同步伺服电机进行直接驱动,其控制问题较常规进给系统更为复杂。因此建立更为科学的适用于直接驱动的永磁同步电机的数学模型对提高旋转进给系统的控制水平具有重要意义。本文提出在矢量控制的基础上建立直接驱动用永磁同步电机的状态空间模型的方法,并运用现代控制理论对系统的能控性、可观测性及稳定性等进行分析和计算以及对系统进行极点配置,并用Simulink进行了系统仿真,为数控机床旋转进给伺服系统的设计和分析提供了理论基础和分析方法。
Rotary feed system such as pendulum head and revolving table of high-powered multicoordinates numerical control machine adopts PMSM to drive directly. It＇s more complex to control than the conventional feed system. So it＇s significative to set up mathematic model of PMSM which is applicable for the direct drive more scientifically in order to improve the control level of rotary feed system. Thus a modeling of PMSM method for state space equation modeling of PMSM based on vector control is proposed. The controllability, observability, stability and Pole assignment are analysed by modern control theory. And the system emulation is finished by Simulink. This method offers theoretical basic and analytical method for rotary feed servo system designing of numerical control machine.
