SimMechanics™ in conjunction with Simulink® and MATLAB® allows engineers to create complicated mechanical models, analyze the models, and develop controllers for the mechanical system. In this technical example, we examine how to use SimMechanics, MATLAB and Simulink to model physical components, synthesize controllers, and simulate the closed loop system of the Stewart Platform. The Stewart Platform is a six-degree of freedom positioning platform.
For more information, see this MATLAB Digest article:

The models provided here originated from the Stewart Platform demo models provided with SimMechanics.

I can not run this program, can you help me please?

For my graduation project I am using the Stewart Platform. To make the simulation more realistic I would like to use a discrete PID controller and this works for a sample time of 0.01 s. But for a lower frequency errors occur because of violated constraints and/or singularities. Would anyone now how to work around this?

Besides this the simulation works very well, thanks a lot!

I downloaded the file but I can't open it in simulink. Simulink is giving this two errors to me : "Failed to load library 'StewartControllers' referenced by StewartPlatform/Controller" and "Unable to open file for reading:"StewartControllers.mdl" " Can anybody help me ? Thanks.

Thanks a lot for such a wonderful work. I'm working with one such modified ver. of stewart
can you please educate me on how to make virtual 3D animation from files imported from solidworks
