Why can't I find the model I need in the simulink?How can I get the demo?

My version is R2018a-academic.

My homework is anlysis the demo "Chopper-Fed DC Motor Drive".The teacher told the reference path is : demo/simulink/simpowersystem/Power Electroics Models/Chopper-Fed DC Motor Drive.

In fact,I search the key words "Chopper DC".I only find 1,2,4-quadrant chopper dc motor.It isn't what i need.

This demo is created by H. Le-Huy (Universite Laval, Quebec) and G. Sybille (Hydro-Quebec)

The demo I need is in the image

.

I get this picture from :https://wenku.baidu.com/view/397752180066f5335a8121e3.html Page:42

So how can i get this demo.

Anyway,THANKS A LOT

R2016b was the last version of the Simscape Power Systems toolbox that includes the model you are looking for ( power_dcdrive_disc ). You can see it listed here: https://www.mathworks.com/help/releases/R2016b/physmod/sps/examples.html.

To get this model you will have to use R2016, and can open it by typing power_dcdrive_disc in the command window.
