[理工] [控制]-穩態誤差..(幫解)()()()()()()Y
1.
4
----- ≦ 2 sec 且 ξ = 0.5
ξWn
ξWn ≧ 2
為什麼 Wn 不能大於等於 4 ...
2.
有人有補詹森題庫嗎..
57頁
24.6 和 146.3
為什麼146.3 不 合
3.
Consider the system with input r(t) , output y(t) , and transfer finction
s + 8
G(s) = ----------------
(s + 2)(s + 4)
(a) Finf the steady-state reponse due r(t) = 2 + 3t
(b) Compute the steady-state error between r(t) and y(t)
b小提 為什麼 為什麼...
2 3
e = -------- + ----
ss 1 + Kp Kv
2 3 15
= ------------------------- + ------------------------ = ---
s + 8 s + 8 8
1 + Lim ------------------ Lim s -------------------
s->0 (s+2)(s+4) - (s+8) s->0 (s+2)(s+4) - (s+8)
^^^^^^^^^
為什麼要減 s+8
15
但是不管有沒有減 我 s 代0 答案都不是 ---
8
