M. Belhadj et T. Aldemir, THE CELL-TO-CELL MAPPING TECHNIQUE AND CHAPMAN-KOLMOGOROV REPRESENTATION OF SYSTEM DYNAMICS, Journal of sound and vibration, 181(4), 1995, pp. 687-707
The cell to cell mapping technique (CCMT) is a numerical technique for
the global analysis of non-linear dynamic systems. The CCMT is partic
ularly useful if the system has a strange attractor. Using a Chapman-K
olmogorov representation of system dynamics, two new CCMT algorithms a
re presented which substantially reduce the computational time and com
puter storage requirements compared to the conventional implementation
of CCMT in the determination of the attractors of the system and thei
r domains of attraction. The new algorithms are also advantageous when
it is difficult to identify a unique probability density function (pd
f) to represent the uncertainty in the system parameters and several p
dfs need to be considered to assess the impact of the choice of the pd
f on the predicted asymptotic system behavior. These features of the n
ew algorithms are illustrated using a second order Duffing oscillator
under harmonic forcing.
