計算結果表明，以多剛體系統動力學的拉格朗日方法所建數學模型模擬精度高，計算效率高，方法可行，多剛體系統動力學模型同模糊pid復合控制策略結合較好，是一個行之有效的進行綜合模擬和優化控制的系統。 -
Abstract : in the field of optical wireless links, concentrators that are designed by the tools of nonimaging optics can be used to collect the light radiation and are more compact and have higher collection efficiencies than imaging concentrators. hemispherical concentrators are studied by ray tracing, then for several normal nonimaging concentrators : hemispherical concentrators, compound parabolic concentrators ( cpc ), dielectric totally internally reflecting concentrators ( dtirc ), simultaneous multiple surfaces concentrators ( sms ) and inhomogeneous media concentrators ( poisson bracket ), the design methods and the performances e. g. the gain and the field of view ( fov ) are compared as well as the application suggestion
文摘:在無線光通信領域，利用非成像光學設計的集中器能夠聚集光輻射能量，而且相對于成像性集中器具有更緊湊的結構和更高的增益.利用光線追跡法對半球形集中器的性質進行了分析與研究.對好幾種非成像集中器:半球形集中器，復合拋物線形集中器，介質內部全反射集中器，多表面集中器，多相介質集中器，從設計原理、增益和視場進行比較，並分析其應用場合
