Stability of linear circuits with interval data: A case study

In this paper we study the problem of checking stability of a class of linear circuits with uncertain parameters. For such circuits the problem is concerned with examination of the eigenvalues of interval matrix. Presented approach is based on checking stability of symmetric interval matrix associated with state matrix. The method is not complex and in some cases we can determine circuit stability. We illustrate the applicability of studied approach by means of two specific examples.
