【 摘 要 】

This paper presents a nonlinear differential equations system linear approximation unstructured additive uncertainty estimation technique. Additive uncertainty linear algebraic and differential equations matrix parameters are estimated using nonlinear and linear differential equations systems time responses through linear programming. The results of proposed approach application are presented.
