  1.

    本文在含時量子系統傳播子的abcd形式理論的基礎上，引入某一方向的束寬、發散角、曲率半徑和品質因子等光束傳輸參數來表徵橫向勢能滿足x和y分量相互獨立的原子激光的傳輸。
  2. The conventional variable structure control technique for uncertain system requires that the uncertainty bound is known as a premise to assure robustness. the requirement creates an over - conservative controller and enlarges chattering. the proposed controller regards the influence of unknown disturbances and parameter uncertainties as an equivalent disturbance and generates an on - line estimation used in smc to cancel the slowly varying uncertainties by the mechanism of time delay. the reaching law approach is used to get the conditions and band of quasi - sliding mode. the new methodology offers a robust feedback control with much lower gains and reduces chattering without a prior knowledge of the uncertainty bounds or matched conditions

    常規變結構控制用於不確定系統，須利用不確定性界確保系統的魯棒性，控制器過于保守且抖振變大.本文把未知干擾和參數不確定性的影響等效為名義系統的外界干擾，利用時延技術對干擾進行在線估計，並將估計值引入到變結構控制中，從而抵消掉系統中的慢變不確定性，利用離散趨近律法，推出了準滑動模態的存在條件及其帶寬.該方法克服了以往控制方法中須已知不確定性界的限制，且不必滿足匹配條件，用較低的控制增益保證了系統的魯棒性，降低了準滑動模態帶即削弱了抖振
