Abstract

The simple and effective method for determining the probability stability of discrete-time systems consisting of two and more random parameters is presented in this paper. Systems with random parameters are often encountered in industry of plastic materials, rubber industry, chemical industry, etc., therefore this method can be applied in practice. The presented method provides the choice of such values of parameters for which the system has the largest probability stability. The selection of the adequate parameters values enables the system stability and the correctness of system work.
