1) the close-loop transfer function is
(s+4)/(s^2+s+3)
and the characteristic equation is s^2+s+3=0.
the real part of the roots of the equation is negtive,
so the system is stable.
2)……
3)……

Variations of the feedback gains with cable length for mt = 0 and the load mass for L =0

inversely proportional to the cable length because the load natural frequency increases with
the length which decreases the system settling time and consequently increases K

对于mt=0的线缆长度和L=0的负载质量,使用减少状态反馈控制器的反馈增益的变化如图4所示.我们可以注意到K反比于线缆长度,因为负载固有频率随线缆长度增加,而线缆长度减少了系统设置时间,结果增加了K值.
不是很准确,有图,参数和公式要好些.还看看其他人的答案吧.

1、初学者
  在多年的学习和教学实践中,我发现初学口语的最有效方法就是背诵英文句型或段落.在背诵前切记要跟着录音带大声朗读5遍以上.有读者会说,我试过了但记不住.其实,背诵时最好有中文译文,一边看句子,一边背.这样就可以确定背不下来是因为情节的连贯问题,而不是因为英语水平的问题.
  2、中级水平
  许多通过了四级或六级的同学只是在阅读、听力或写作方面有能力,并不代表口语也有相应的水平.大家不要认为自己学的口语教材简单,可以做个试验:拿一篇你认为很浅显的文章,将其翻译成汉语,让别人将每句汉语读给你听,然后你再翻译成英文.如果没问题,说明你口语很好,否则就需要多做这种练习.
  3、特别方法
  (1)每晚入睡以前躺在床上,用英文对自己自言自语,将一天发生的事情描述下来.要持之以恒
  (2)同一个英文对白的电影,每星期至少看一次,连续三个月以上,不要看不同的,口语一定大有进步

feed 是喂养,喂食;相当于”馈”,左边为食字旁;

这句话的主语是all,没有谓语,没有宾语或者表语.
few risks being taken是作为现在分词做状语,表示条件.可以放在前面或者后面.放在前面是表强调条件.
整个句子意思是:不需承担多少风险,所有的都可以得到快速反馈.
如果你说:Few risks are taken,all with rapid feedback.这就是两个句子了.那就是:Few risks are taken.All with rapid feedback.这样的话,两个句子意思都不通了.因为这本来就是一个句子.只是这个句子只有主语all而已
