Based on these, an improving μ-synthesis is presented, with which the high-purity distillation is designed well. 2. The robust performance problem of MIMO plant is explained with the plant direction angle, which shows that the robust performance varies with different input uncertainties and the μ-synthesis should be applied correctly according to the uncertainty structure. 3. Condition number and bandwidth are the important items for robust performance design in MIMO system. The H〓 two-block problems can not deal with the robust performance design of MIMO system because of the condition number cancellation. A general μ-synthesis procedure for MIMO system with uncertainties is presented. 4. For the SISO system, the object function in robust performance is amplified by at most 〓 than that of H〓 two-block problems in value: So the robust performance of SISO system can be done with the H〓 two-block problems to avoid the complicated μ-synthesis procedure. 5. All the conclusions and methods presented in this paper are demonstrated by some typical design examples.

从而形成一种改进的μ综合方去,并对精馏塔病态对象进行了鲁棒性能设计,得到令人满意的结果;(2)利用对象的方向角解释了MIMO对象鲁棒性能设计出现问题的原因,并提出不同输入摄动形式下系统的鲁棒性能问题也并不相同,因此利用μ综合处理鲁棒性能设计时,应根据不同的摄动情况采用不同的结构进行设计:(3)条件数问题和带宽问题是MIMO系统鲁棒性能设计的两个主要问题,指出由于条件数对消的存在使得一般H〓两块问题无法处理MIMO系统的鲁棒性能设计,而μ综合方法则是处理MIMO系统鲁棒性能设计的有效方法,并给出了其处理MIMO系统鲁棒性能设计的一般性方法;(4)提出对于SISO系统H〓两块问题(S/T问题、S/KS问题)的设计指标函数与鲁棒性能设计的μ指标函数在数值上最大差〓倍,因此对于一般SISO系统的鲁棒性能设计可以简单地用一般的H〓的两块问题处理,而避免μ综合设计的复杂过程;(5)本文中提出的结论和算法都利用H〓/μ发展中的典型例子:Doyle-Stein问题,Safonov的战斗机模型,精馏塔对象等进行了设计验证。

This paper introduces the studies of the ultra-short Thomson scattering X-ray source at the accelerator laboratory of Tsinghua University in recent years. Properties such as the photon yield,the pulse length and time jitter of the produced photon pulse were predicted theoretically from the parameters of the electron bunch and the laser pulse,and the scattering angle. Preliminary experiments were successfully carried out with a 16 MeV backward-traveling-wave accelerator and the ns-Q switched laser provided by China Academy of Engineering Physics. This paper also introduces the 1.6-cell electron gun that was fabricated on site and the experiment with high RF power including the measurement of the electron bunche parameters. Based on these,we have designed an X-ray source,which is now under construction.

She took part of our overseas on-location shooting sessions a couple times in the past 2 years. I found out this attractive lady likes to sneak around behind our backs and shoot with an electronic viewfinder digital camera while we were working. I dispatched her a Nikon D40x DSLR with a professional grade super wide-angle zoom lens on a recent trip to Mindoro and Palawan (both are provinces of the Philippine), even though she is not a photographic assistant to me. Moreover, that camera body I gave her was just becoming available and right out of the box at that time. Yes, brand new stuff!
