摘要：

In　order　to　suppress　the　inherit　force　ripple　of　Permanent　Magnet　Linear　Synchronous　Motors　to　get　a　smooth　velocity　response,　a　compensation　method　based　on　NESO　is　proposed.　The　disturbances　including　force　ripple　are　online　observed　by　the　NESO　and　compensated　by　a　feed　forward　component.　At　the　reference　velocity　of　0.1　m/s,　the　fluctuation　range　decreases　from　6.75%　to　1.23%.　Both　simulation　and　experimental　results　showed　that　the　influence　of　the　force　ripple　is　effectively　reduced,　and　thus　resulted　in　a　smoother　velocity　response.
