22. 承 21 題 ; 則其輸入輸出轉移函數 ( input-output transfer function ) G(s) = ?(A) G(s) = 2/(s+1)(B) G(s) = (2s+3)/((s+1)^2)(C) G(s) = 3/((s+1)^2)(D) G(s) = 1/((s+1)^2)

25. 某系統之動態方程式為 \(\dot{\mathbf{x}}(t) = \begin{bmatrix} 0 & 1 \\ -1 & -2 \end{bmatrix} \mathbf{x}(t) + \begin{bmatrix} 0 \\ 1 \end{bmatrix} u(t), y(t) = \begin{bmatrix} 0 & 1 \end{bmatrix} \mathbf{x}(t), \mathbf{x}(t)\) 為狀態向量, \(y(t)\) 為輸出。若以 \(u(t) = -[k_1 \quad k_2] \mathbf{x}(t)\) 作回授控制, 而閉迴路系統為穩定時, \(k_1\) 及 \(k_2\) 之限制為何?(A) \(k_1 > 1\) 且 \(k_2 < 1\)(B) \(k_1 < 1\) 且 \(k_2 > 1\)(C) \(k_1 > -1\) 且 \(k_2 > -2\)(D) \(k_1 > -2\) 且 \(k_2 > -1\)
