Computational Analysis for the Dynamical System Associated to an Access Control Structure

This paper presents some analytical considerations regarding the dynamical behavior of an access control structure, based on the mathematical model associated to this structure. This structure type is largely analyzed in the literature. A modern approach of this structure based on SMA (shape memory alloy) is taken into account, because of some particular advantages: unique characteristics (superelastic effect, as well as the single and double shape memory effects), damping capacity of noise and vibration, resistance to fatigue, diversification of the control and command possibilities.

The basic aim is the qualitative analysis of the mathematical model associated to this structure. Namely, the dynamic system associated to the variation of the angle q describing the position of the access control structure is analyzed from the influence of parameters standpoint. The MAPLE11 soft is used in order to evaluate the behavior of the equation solution with respect to the parameters variation.

This analysis produces a data collection which is useful both for further developing a fuzzy logic controller for the active control of this access structure and for further refinements of the mathematical model associated to this structure type.
