Resumo(s)
The coefficient diagram method (CDM) is one of the easiest
methods for model based control system design. Its core is based on
an algebraic method but it also encompasses a graphical analysis diagram
that helps the user to evaluate the three main closed-loop system
requirements: dynamic behaviour, robustness and stability. This later
characteristic is analysed by a set of stability conditions derived from
the previous work of Lipatov and Sokolov on sufficient conditions for
stability. However, in CDM, only a fraction of the total conditions are
considered. This work will show that this fact increases the inconclusive
area within the stability space. Moreover an extended set of CDM stability
conditions, in conjunction with its graphical interpretation, will be
presented
