D-decomposition analysis of automatic control systems

Development of the basic theory of D-decomposition by a general polynomial expression, the characteristic function of a linear lumped parameter automatic control system, is followed by account of: the basic theory of parametric stability; unity-feedback variable-gain analysis, with subsequent generalization to numeric and frequency-dependent feedback; transient response determination; and sampled-data system analysis, as effected by D-decomposition theory. Application of theory in practice is illustrated by numerous illustrative examples.
