A New Method for Parameter Sensitivity Analysis of Lorenz Equations

Abstract EN

A new method for parameter sensitivity analysis of Lorenz equations is presented.

The sensitivity equations are derived based on the staggered methods.

Experimental results indicate that it is possible to determine effects of parameters on model variables so that we can eliminate the less effective ones.

Robustness can also be verified in some confidence intervals by simply looking at the corresponding phase portraits.

This enables us to control the system.

Although the stability properties of the Lorenz equations are studied extensively, to the best knowledge of the authors, the PSA of Lorenz equations has not been considered which is the main goal of this paper.
