P, PD, PI, PID Control 2P T1T2 Step Disturbance Response
Applet shows the step disturbance response of a type 0 system with P, PI, PD and PID control.
P(Orange) and PD(Cyan) control produces a change of 1/(1 + K) in the output with a unit step diturbance. With PI(Red) and PID(Green) control the initial change produced by the disturbance decays to zero. The parameter values (3.0, 1.0, 1.0, 1.0, 3.0, 4.0, ...) shows that for PI and PID the change produced by the disturbance decays to 0 after ~ (4 - 5) x Ti.
