PI Control Step Response and Nyquist Plot for 1PT0

Cuthbert Nyack
Applet shows the frequency response(Nyquist plot) of a first order type 0 system with PI control.

The eg parameters (5.0, 1.0, 2.0, 0.4, 1.0, 1.0) show a reasonable step response and the increased lag of the PI controlled system.
Eg parameters (2.0, 1.0, 0.1, 1.0, 1.0, 3.0) show what happens when Ti < T1.
Parameters (5.0, 1.0, 1.0, 0.4, 1.0, 1.0) show Ti = T1.



Gif image below show how the applet should appear.
