This paper(PART 1)presents the general principle of the stability equation method. A detail proof of a criterion for predicting the locations of roots of polynomials with real or complex coefficients is given and comparisons with other methods are considered. Following this paper, additional papers will be presented concerning the applications of the stability-equation method to various engineering problems.

Methods for computing the roots of polynomial equations with complex coefficients by use of the stability equations are presented in this paper. Based upon the presented methods, computation routines arewritten, which can be used to solve polynomial equations with-complex coefficients by dealing with real numbers only. In comparison with current methods the advantages of the presented methods are given, and applications to the analysis and design of control systems are considered.
