However, from the point of contents, today's Internet still does not enable to communicate much more than print - words and pictures (albeit dynamic and generated on-the-fly from a database). However, people think in concepts and laws when reasoning about real world things and systems. We propose how these concepts as well as things could be represented on Internet in a live and working form, developed, shared and used for practical purposes by all Internet users. This approach would lead to a cooperative development of an environment containing the Common Sense (similar to Wikipedia, but in a live computational form) and to the seamless interconnection between the real world things and their virtual counterparties - e-things on Internet.

A triple integrator plant has been used to illustrate the design. The paper is focused on the synthesis in a computer algebra system MAPLE, which is shown "step by step" in the paper. The designed control can be applied to a broader class of systems.

The design combines the well known time optimal control with the linear pole assignment control, i.e. the control consist of n phases similar to the time optimal control, however the transients between these phases are "smooth" and the dynamics of the transients is given by the closed loop poles.
