Tracking control for permanent-magnet linear synchronous motor based on parsimonious learning feed-forward control

LIU Lili(Department of Electronics and Information Engineering,Suzhou Vocational University,Suzhou 215000,China)  
For the characteristics of permanent-magnet linear synchronous motor(PMLSM) suffering from the effects of end effect,load disturbances and parameter variations and so on,the parsimonious learning feed-forward control(LFFC) with learning filter was designed.The learning feed-forward compensation based on several lower-dimensional B-spline networks was adopted to overcome the influence of the end-effect,and a learning filter was added to the learning feed-forward controller to ensure stability of the system.Simulation results show that the proposed strategy enables servo system to have accurate tracking performance for non-periodic input signal,while solves effectively the "curse of dimensionality" in learning feed-forward control.
