Abstract
The problem of building the stability space for third-order control system is solved. The 3D stability space has coefficients of characteristic equation as coordinates. Analytical conditions of system stability are defined. Different variants of crossing of stability border surface by coefficients of characteristic equation are considered. The analysis of changes in location of roots of system characteristic equation and in types of step responses under these variants is fulfilled.
