This paper analyzes five sorts of simulated inductances, and expound their single characters and their adaptability situations, it provides the concrete measures of improving the characters of simulated inductances.

Thus,we develop the principle with the simulated inductor instead of inductor.

In this paper, Chua s circuit and its characteristics, as well as the circuit of realizing non-linearity resistance are firstly described; And then, a simulated inductor composed of op amps, linear resistances and capacitances is designed, Chua circuit is also improved by means of simulated inductor with good results obtained.

Thus,we develop the principle with the simulated inductor being instead of inductor.

The experiment study of multiscroll chaotic circuit based on a stimulated inductor circuit;

The experiment study of chaos and chaotic control by means of stimulated inductors

Secondly, a stimulated inductor circuit is introducted.

Simulated inductance based on MDDCC;

This paper is on the basis of the realized method which introduces active simulated inductances, using the active simulated inductances to replace ideal inductances to make research of the realization of integrative chaotic signal generator.

A sinusoidal oscillation circuit composed of simulated inductance and negative resistance converter is put forward according to the principle of simulated inductance and negative resistance conversion.

On the basis of traditional band-pass filter with coupled tunability, the basic cercuit modes of a V-I coverter, a analog resistor, a earthed and a floating-earthed analog inductance were all given by CCCⅡ.

In this paper,by detailed narrations of structure of moveing-felt simulator,the component of virtual reality,the numerical control model of moving-felt platform,and our some research work in the technology of combination between virtual reality and the moving-felt simulator have been introduced,and we also development direction of virtual reality in the future.
