In this paper the problem of stability analysis of linear closed-looped systems under interval uncertainties is considered. The problem is reduced to the problem of determining outer bounds on the ranges of the eigenvalues of interval matrices with dependent coefficients with respect to the independent elements of all other interval matrices ...

In this paper, the problem of numericaly mining the steady-state in asinchronous mashines is considered. Based on a appropriate mathematic model the original problem is reduced to a system of four nonlinear algebraic equations. The solution of the latter system is obtained using an efficient interval method which guarantees convergence and ...

In this paper, the worst-case tolerance analysis of dc linear electric circuits is lered. A simple method for handling the problem is sugested which reduces to inverting tatrices and solving one system of linear equations. The method is more efficient comonwise than other known methods, providing solutions of sufficient accuracy.
