Lab 1:   Introduction to Simulink
Lab 2:   Open and closed-loop control of a single-phase motor
Lab 3:   Modelling of the brush DC motor (Lab3.mdl)
Lab 4:   Control of a brush DC motor (again Lab3.mdl)
Lab 5:   Open-loop control of a stepper motor (Lab5.mdl)
Lab 6:   Brushless DC motor control with six-step commutation (Lab6.mdl)
Lab 7:   Position control of a brushless DC motor (Lab7.mdl)
Lab 8:   Slip control of induction motors (Lab8.mdl)
Lab 9:   Field-oriented control of induction motors (Lab8.mdl)

Recommendations for the simulations:
In the Simulink window, select Simulation/Model Configuration Parameters.
  A configuration window opens, select Commonly Used Parameters and Data Import/Export.
  Then, in Format, select Array. Also, uncheck Single simulation output.
Be sure to convert deg to rad and rpm to rad/s (and vice-versa) when needed.
  In particular, the angles of cos and sin functions in Matlab must be expressed in rad.

Note that properties of an existing figure can also be adjusted by clicking on File/Preferences/Figure Copy Template
  and Apply to Figure.

Simulink tutorial videos

The tutorials below show how to perform the tasks of Lab 1, in addition to giving useful information of general interest.
The tutorials and the mdl files were developed using version 2017A of Matlab/Simulink.
Some details may have changed and need to be adjusted with newer versions.

Simulink tutorial - Part 1 (mp4) (wmv)  simulation of a first-order linear time-invariant system
Simulink tutorial - Part 2 (mp4) (wmv)  implementation of a PI controller, viewing signals on a scope, and embedded m-files
Simulink tutorial - Part 3 (mp4) (wmv)  useful settings and additional features
Simulink tutorial - Part 4 (mp4) (wmv)   saving figures and block diagrams for reports
