loop transfer function การใช้

The loop transfer function in this case is:
The system is called unstable where the closed loop transfer function diverges for some s.
Bode's ideal loop transfer function is probably the first design method that addressed robustness explicitly.
When this suppression vanishes, the parasympathetic system may overreact, as typical for any Closed-loop transfer function.
By extension, a closed loop transfer function which has all poles of the transfer function at the origin is sometimes called a dead beat transfer function.
