In this paper is showed a didactic tool for the automatic control teaching based on the inverted pendulum on sliding car, which is developed in a virtual prototype, simulating the nonlinear model in M atlab and presented the result in the java 3D environment. To give solution to the control problem it is necessary to have in consideration two principal and important aspects asthe swing up (to take the pendulum to vertical position) and the swinging (to maintain the pendulum in the vertical position). The graph user interface (GUI) searches to facilitate the learning of the basic concepts of a control system for ungraduate and posgraduate students, searching to minimize costs and time in the teaching.
