A　novel　nonlinear　integral　sliding　mode　(NNISM)　control　strategy　for　maximum　wind　energy　capture　of　doubly　fed　induction　generator　(DFIG)　control　is　proposed.　Some　elements　such　as　poor　wind　speed　transient　performance　or　low　wind　energy　capture　efficiency　under　the　condition　of　low　wind　speed　fluctuation　can　be　improved　by　using　the　new　type　of　maximum　power　point　tracking　method.　With　self-saturation　characteristics,　the　parameters　of　nonlinear　integral　sliding　mode　controller　can　be　adjustable　and　the　chattering　can　be　avoided　with　the　nonlinear　potential　energy　function　that　can　avoid　the　effect　of　integral　supersaturating.　Considering　the　wind　energy　utilization　coefficient　and　the　maximum　tip　speed　ratio　of　the　wind　turbine,　the　optimal　speed　setting　value　of　the　DFIG　under　the　optimal　tip　speed　ratio　is　calculated　in　order　to　maintain　the　maximum　wind　energy　utilization　of　the　system.　Simulation　results　show　that　the　control　performance　of　the　NNISM　control　strategy　will　not　degrade　in　the　condition　of　low　wind　speed　or　fluctuated　wind　speed,　and　the　speed　overshoot　is　small.　With　fast　following　speed　and　strong　robust　performance,　it　can　achieve　the　control　target　of　maximum　wind　energy　capture　and　has　broad　application　prospects.　©　2020,　Editorial　Office　of　Journal　of　Xi＇an　Jiaotong　University.　All　right　reserved.
