Process diagram and unit elements allocation:

Unit control may be done manually, on the unit itself, basically or in a more advance way through the control software SCADA. This control software can do two kinds of control:

Open-loop and Closed-loop control.
The base unit has four different parts as seen on the front panel:
- Connection zone for motor and tachogenerator.
- Manual or Compute rised Speed control. There is a lever-like switch for selecting the kind of control.
- PID zone. Here, the values of the PID constants can be manipulated (Proportional, Integral and Derivative).

This functionality is only available for PC mode, the speed control lever has to point to PC.
- Turning and stop control zone. Allows changing the turning sense and stopping the motor.
Simple integrated circuits to be able to analyse independently each functional stage.
Visible components with 2 mm connectors for voltage and current measurement.
Control through PWM pulses and power stage configured with MOSFET transistors.

Exercises and practical possibilities:

Some Practical Possibilities of the Unit:

1.- Open loop control response.
2.- Demonstration of a bracking ramp functioning.
3.- Functioning of a PWM modulator and the response of the system.
4.- Closed loop or feedback control through a Proportional control (P).
5.- Closed loop or feedback control through a Derivative control (D).
6.- Closed loop or feedback control through a Proportional-Integral controller (PI).
7.- Closed loop or feedback control through a Proportional- Derivative controller (PD).
8.- Achievement of an over damped system using a closed loop system.
9.- Achievement of a critically damped system using a closed loop PID.
10.- Instability, a characteristic of closed loop systems.
11.- Stabilisation of an unstable system.
12.- Faults simulation:

Type of faults including on the unit:
Fault 1: The absolute value of the feedback signal from the
tachogenerator is not calculated for its subtraction
from the reference, thus, for one of the turning
senses, the error is wrong.
Fault 2: The value of the Proportional constant of the PID is
divided by ten with the user unable to detect it but its
effect.
Fault 3: The value of the Integral constant of the PID is
divided by ten with the user unable to detect it but its
effect.
Fault 4: The value of the Derivative constant of the PID is
divided by ten with the user unable to detect it but its
effect.
Fault 5: The signal from the tachogenerator is modified,
making the PID control to believe that the speed is
ten times lower to the real one.
None of these faults are exclusive, being possible to
combine them.
