Example 4: PID parameters adjustment

Assume that the transfer function of the controlled device G(S) in a control system is a first-order

(model of general motors), SV = 1, and sampling time (T

) = 10ms. Suggested

steps for adjusting the parameters are as follows:

as 5, 10, 20, 40. Record the SV and PV respectively and the results are

as the figure below.

0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1
