常规变结构控制用于不确定系统，须利用不确定性界确保系统的鲁棒性，控制器过于保守且抖振变大.本文把未知干扰和参数不确定性的影响等效为名义系统的外界干扰，利用时延技术对干扰进行在线估计，并将估计值引入到变结构控制中，从而抵消掉系统中的慢变不确定性，利用离散趋近律法，推出了准滑动模态的存在条件及其带宽.该方法克服了以往控制方法中须已知不确定性界的限制，且不必满足匹配条件，用较低的控制增益保证了系统的鲁棒性，降低了准滑动模态带即削弱了抖振 | | 3. | The methods and the experimental setups for measuring the gain and noise figure of an edfa are emphasized . we introduce how to measure the characteristics of each component of an edfa , especially the gain and absorption coefficient of an erbium doped fiber ( edf ) . thirdly , four types of simple and novel l - band edfa structures with low noise , high gain and low gain ripple are proposed to satisfy the requirement of a dwdm system

文摘:常规变结构控制用于不确定系统，须利用不确定性界确保系统的鲁棒性，控制器过于保守且抖振变大.本文把未知干扰和参数不确定性的影响等效为名义系统的外界干扰，利用时延技术对干扰进行在线估计，并将估计值引入到变结构控制中，从而抵消掉系统中的慢变不确定性，利用离散趋近律法，推出了准滑动模态的存在条件及其带宽.该方法克服了以往控制方法中须已知不确定性界的限制，且不必满足匹配条件，用较低的控制增益保证了系统的鲁棒性，降低了准滑动模态带即削弱了抖振 | | 5. | It is thus of importance to develop an l - band edfa . however , a conventional l - band edfa is relatively inefficient and has low gain and high noise figure since they are operated at the tail of the erbium gain band . therefore , it is very important to design and analyze a high performance l - band edfa with simultaneously high gain , low noise and low gain ripple for a dwdm system
开发新的l - bandedfa是十分必要的，然而传统的l - bandedfa由于工作在铒光纤增益谱的尾部，其存在增益低、工作转换效率低、噪声大等缺点，因此，分析和设计符合dwdm系统发展要求的具有优良性能(高增益、低噪声、动态增益均衡)的l - bandedfa是十分有意义的。 |
