%0 Journal Article %T Sensitivity analysis for differential algebraic equations %A G. Boroni %A P. Lotito %A A. Clausse %J Latin American applied research %D 2008 %I Scientific Electronic Library Online %X In this paper we propose a new method based on adjoint systems for parametric sensitivity analysis of DAE's. This method is employed in a series of experiments, and the results are compared with the estimation of sensitivity by a finite differences method, widely used because of the simplicity of its implementation . In addition, we propose a method extension based on the use of estimation functions that allows transforming the original adjoint system into an algebraic system, making it suitable for many efficient numerical methods. %K Simulation %K Parametric Sensitivity %K DAE System %U http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S0327-07932008000200004
