Simulink® and Simulink Projects provide a collaborative, scalable environment that enables teams to manage their files and data in one place.
< / p >
< p >
With Simulink Projects, you can:
< / p >
< ul class = "org-ul" >
< li > < b > Collaborate< / b > : Enforce companywide standards such as company tools, libraries, and standard startup and shutdown scripts. Share your work with rich sharing options including MATLAB® toolboxes, email, and archives.< / li >
< li > < b > Automate< / b > : Set up your project environment correctly every time by automating steps such as loading the data, managing the path, and opening the models.< / li >
< li > < b > Integrate with source control< / b > : Enable easy integration with source control and configuration management tools.< / li >
< / ul >
< / blockquote >
< p >
The project can be opened using the < code > simulinkproject< / code > function:
< / p >
< div class = "org-src-container" >

< / pre >
< / div >
< p >
When the project opens, a startup script is ran.
The startup script is defined below and is exported to the < code > project_startup.m< / code > script.

When the project closes, it runs the < code > project_shutdown.m< / code > script defined below.
< / p >
< div class = "org-src-container" >

A < a href = "https://.mathworks.com/products/simscape.html" > simscape< / a > model permits to model multi-physics systems.
< / p >
< p >
< a href = "https://mathworks.com/products/simmechanics.html" > Simscape Multibody< / a > permits to model multibody systems using blocks representing bodies, joints, constraints, force elements, and sensors.

< div class = "outline-text-3" id = "text-2-1" >
< p >
Each solid body is represented by a < a href = "https://mathworks.com/help/physmod/sm/ref/solid.html" > solid block< / a > .
The geometry of the solid body can be imported using a < code > step< / code > file. The properties of the solid body such as its mass, center of mass and moment of inertia can be derived from its density and its geometry as defined by the < code > step< / code > file. They also can be set by hand.

< div class = "outline-text-3" id = "text-2-2" >
< p >
Frames are very important in simscape multibody, they defined where the forces are applied, where the joints are located and where the measurements are made.
< / p >
< p >
They can be defined from the solid body geometry, or using the < a href = "https://mathworks.com/help/physmod/sm/ref/rigidtransform.html" > rigid transform block< / a > .

< div class = "outline-text-3" id = "text-2-3" >
< p >
Solid Bodies are connected with joints (between frames of the two solid bodies).
< / p >
< p >
There are various types of joints that are all described < a href = "https://mathworks.com/help/physmod/sm/ug/joints.html" > here< / a > .

For each of the joint primitive, we can specify the dynamical properties:
< / p >
< ul class = "org-ul" >
< li > The < b > spring stiffness< / b > : either linear or rotational one< / li >
< li > The < b > damping coefficient< / b > < / li >
< / ul >
< p >
For the actuation, we can either specify the motion or the force:
< / p >
< ul class = "org-ul" >
< li > the force applied in the corresponding DOF is provided by the input< / li >
< li > the motion is provided by the input< / li >
< / ul >
< p >
A sensor can be added to measure either the position, velocity or acceleration of the joint DOF.
< / p >
< p >
Composite Force/Torque sensing:
< / p >
< ul class = "org-ul" >
< li > Constraint force< / li >
< li > Total force: gives the sum across all joint primitives over all sources: actuation inputs, internal springs and dampers.< / li >
< / ul >

A transform sensor block measures the spatial relationship between two frames: the base < code > B< / code > and the follower < code > F< / code > .
< / p >
< p >
It can give the rotational and translational position, velocity and acceleration.
< / p >
< p >
The measurement frame should be specified: it corresponds to the frame in which to resolve the selected spatial measurements. The default is < code > world< / code > .
< / p >
< p >
If we want to simulate an < b > inertial sensor< / b > , we just have to choose < code > B< / code > to be the < code > world< / code > frame.
