WebGL Presentation of Three Tank System

The paper describes an educational tool that enables to present a typical laboratory model of three tank system in the Internet environment. The model is realized in the form of WebGL animation and is interactive. By opening and closing valves it enables students to change its dynamical behavior. In addition, the model is complemented by PID controller where user can set up proportional, integral and derivative term according to own controller design. The background of the whole web application is driven by ScicosLab simulation environment.
