A　three-plate-type　polarization　state　generator　(PSG)　was　designed　and　the　transformation　of　Stokes　parameters　was　derived　according　to　the　structure　characteristics　of　PSG.　Based　on　the　principle　of　Tabu　Search　(referred　to　as　TS)　algorithm,　a　control　algorithm　was　proposed　which　was　able　to　not　only　achieve　the　rapid　transformation　between　the　polarization　states　but　also　reduce　the　bias-voltage　across　the　crystal.　The　simulation　results　show　that,　by　using　this　control　algorithm,　the　PSG　can　transform　the　linear　polarization　into　arbitrary　polarization　and　the　precision　can　arrive　to　0.07%.　If　the　Stokes　parameter　S2　and　S3　were　restricted　to　the　specific　region　on　the　Poincare　sphere,　the　desired　polarization　state　was　generated　by　this　control　algorithm　and　the　control　voltage　amplitude　was　ensured　within　120　V.　Last,　the　experimental　results　show　that,　this　control　algorithm　could　satisfy　the　requirement　of　encoding　in　continuous　variables　coherent　optical　communication　of　single　beam.　©,　2015,　Chinese　Society　of　Astronautics.　All　right　reserved.
