Velocity control of an electric engine with Automatic Tuning
Description
Velocity control of an electric engine with a PI
controller.
The PI controller regulates the voltage source of the electric
engine, and measures its angular velocity (corrupted by noise). The
aim of this example is to show how a controller with Automatic
Tuning can be used in a real context.
In the following table are listed the controller parameters before
and after the Automatic tuning

The figure below show the velocity set point, the measured process
variable and the control signal, that is limited between 0 and 24
V.
