Individual Project Requirements:

 

To create a model with a voltage input and outputs of a) current, position and velocity b) position and velocity for a permanent magnet DC motor using the System Identification Toolbox and then verify it using step pulse and triangle signals.

 

Parts used:

 

• xPC target;

• National Instruments 6024E card;

• DC motor;

• DC motor driver;

• Hook-up wires.

 

Procedure:

 

First, DC motor state-space model was derived for part a) and b).

 

State-space model for part a):

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

State-space model for part b):

 

 

 

 

 

 

 

 

 

 

Then the white noise signal was sent to motor driver and output of current, position and velocity values measured. Then the data was imported to System Identification Toolbox and state-space model extracted.
