Mathematical Modelling
The goal in the development of the mathematical model is to relate the voltage
applied to the armature to the velocity of the motor. Two balance equations can be
developed by considering the electrical and mechanical characteristics of the
system.
DC motor modelling
in SIMULINK
•
At first we need to open MATLAB SIMULINK
•
Form the internal library of SIMULINK we need to import block of necessary equipment.
•
For our model we need the following equipment :
1.
2 constant power supply block
2.
2 gain block
3.
2 adder block
4.
2 discreet transfer function block
5.
2 display block and 1 scope block
DC MOTOR MODEL
After arranging the blocks in order and giving connection between them.

WAVEFORMS
In motoring mode as the time goes we get a higher output

WAVEFORMS
In breaking mode as the time goes we get a output of 0 to negetive
