예제 예제 보드선도

다음 시스템에 대한 보드선도를 그려라.

1. $G(s) = \dfrac{10 (s+2) }{ s ( s+5)}$

import numpy as np
import matplotlib.pyplot as plt
import control as ct

G1 = ct.tf([4],[1])
G2 = ct.tf([0.5, 1],[1])
G3 = ct.tf([1],[1, 0])
G4 = ct.tf([1],[0.2, 1])
G = ct.series(G1, G2, G3, G4)
ct.bode(G)

2. $$G(s) = \dfrac{1000 (s+1) }{ (s + 10) ( s+100)}$$

3. $$G(s) = \dfrac{6 }{ s (s+1)(s+3)}$$

4. $$G(s) = \dfrac{5 (s+4) }{ s^2 (s+10)}$$

5. $$G(s) = \dfrac{16 }{ s^2 + 2.4s+16}$$

6. $$G(s) = \dfrac{25 }{ s^2 + 4s+25}$$

7. $$G(s) = \dfrac{5(1+0.1s)}{s(1+0.5s)\left({1+ \dfrac{0.6}{50}s + \dfrac{1}{50^2}s^2 }\right)}$$
