In this chapter, st ability and performance for multivariable systems with uncertainty will be considered. Consider a general multivariable system as depicted in Figure 5.1. All signals will in general be vectors, and G() and K(s) will be transfer matrices. d(s) is an output distur- bance signal and n() represents

第一题: 1.y(t)=u(t-t) 使用拉式变换的定义: Y(s)=\u(t-r) 令T=t-T, Y(s)=Se-ru()= u()dt=(s) 所以,G(s)=ex

第一题 已知传递函数为G(s),输入r(t)= Asinwt使用部分分式法和复数法,证明稳态输出为:

Rhythm in English speech is based on stress. rhythm unit节奏单位)is formed by stressed syllable, together with unstressed syllables which may come before the stress and after it.The unstressed syllables before the stress are said very quickly, so they are very short, as short as you can make them; but the stressed syllable is as long as before, so there is great difference of length between the unstressed syllables and the stressed one, e.g
