【Abstract】 In order to deal with large position tracking errors of the PMSM servo system duringhigh speed feeding,a new position feed-forward control scheme is proposed.The model forposition controller and the strategy of realizing the servo operation with software are de-scribed.It is proved by experiment that high precision control can be achieved without af-fecting system stability.更多还原
