This paper proposes a Web-based architecture to monitor and experiment a Digital Pendulum Control System from a remote place. The Digital Pendulum Control System is an interesting educational tool considered ideal for both laboratory and project work, and a typical case of a computer control application.

Recent growth in the WWW (Word Wide Web) and Java has received significant attention as means to share sophisticated and expensive laboratory equipment in Computer Engineering Courses. To share a Digital Pendulum System in class laboratory and with other educational institutions, this paper proposes an Internet Toolkit for Computer Engineering Courses. This allows the monitoring and experiment of a Digital Pendulum System from remote place. A simple and easy-to-use Web interface was developed to help students, and other users, in lab experiences using default control algorithms.

This paper proposes a Web-based toolkit to monitor and experiment a Digital Pendulum Control System from any host of an intranet. “The Digital Pendulum Control System is a modern version of a classical control problem: that of balancing a free swinging pendulum in its inverted position”.

O presente trabalho visa o desenvolvimento de uma aplicação que permite a partilha de um equipamento didáctico existente, neste caso na Escola Superior de Tecnologia de Castelo Branco, via Internet, tornando possível realizar, de forma interactiva, experiências de controlo a partir de um local remoto (na sala de aula, outra sala de aula ou do exterior). O equipamento didáctico é o sistema Pêndulo Digital que opera num ambiente Matlab/Simulink, e juntamente com a toolbox Pendulum da Feedback [Fdb], fabricante do pêndulo, permitem controlar o sistema e realizar experiências através da alteração de parâmetros predefinidos (Figura 1). Este equipamento permite a aplicação de diversos algoritmos de controlo ao pêndulo, tais como o algoritmo baseado em regras (Rule-Based), o algoritmo PID, etc.
