Google colaboratory

This is an entry about my Google Colaboratory documents.

Google colaboratory allows you to execute Python code in virtual machines so that it is possible to execute and share code without having owning a Python execution environment. You just need to have a browser.

Colaboratory documents are Python Jupyter notebooks that allow you to include not only code but also text, formulas and images.

The colaboratory documents can be downloaded on your computer as Jupyter .ipynb documents and executed offline in a localPython evironment.

To access colaboratory you need to have a Google account. This is enough to see the documents, but if you want to execute your content, you must save a copy in your own Google Drive account.

Below yoy can find links to some documents created in Colabortory. They all import a Python calc module that includes support functions such as, for example, plot11, plot1n and plotnn that assist in curve drawing. The module is accessible thanks to GitHub.

The colaboratory document list is constantly updated. The current list of documents is accessible my Master Colaboratory Document.

What follows is a list of currently available documents. See the previous list for an updated list.

The documents organized by categories. 

Control

Documents related to mechanical and control subjects

Pendulum
Document that explains the physical behavior of a pendulum and that allows to simulate it.

DC Motor
A document that explains how a DC motor works and also allows you to simulate its dynamic behavior.

Inverted pendulum
A document that deals with the control of an inverted pendulum, which is intrinsically unstable, and which explains how it can be stabilized using a PID controller and an electric motor.
