Hello, I have some question about Step resoponse Comment,
once, I want to plot about open loop system only use Transfer function,
For example for 1/(s+3) sytem, when I plot,
then the Final value of step response is 0.333, So Steady - State error around 0.667
When calculate steadt-state error is fisrt ordher system, We use 1/(1+Kp),
So in this system, Kp = 1/3, So Ess have to be 0.75.
Why is that differenet ??
