伝達関数（連続）【control】

伝達関数

control.matlab.tf() 関数を用いて、伝達関数で与えられたモデルを作ることができる。

code:tf1.py

from control import matlab as ctmt

G1 = ctmt.tf(1, 2, 3)

print(G1)

結果

code:result1.txt

<TransferFunction>: sys0

Inputs (1): ['u0']

Outputs (1): ['y0']

-------

2 s + 3

一次遅れ要素、二次遅れ要素

$ G_1(s) = \frac{K}{Ts + 1}, G_2 = \frac{K \omega^2_n}{s^2 + 2\zeta \omega_n s + \omega_n^2}

code:tf2.py

from control import matlab as ctmt

K1 = 1

T = 1

G1 = ctmt.tf(K1, T, 1)

print(G1)

K2 = 2

zeta = 1

omega = 1

print(G2)

結果

code:result2.txt

<TransferFunction>: sys0

Inputs (1): ['u0']

Outputs (1): ['y0']

-----

s + 1

<TransferFunction>: sys1

Inputs (1): ['u0']

Outputs (1): ['y0']

-------------

s^2 + 2 s + 1
