INTRODUCTION TO MATHEMATICAL DIAGNOSTICS I. THEORETICAL BACKGROUNDS

Technical state of the dynamical system can be identified by the means of the changes of the so called (measurable) external and (non-measurable) internal parameters. One of the main goals of mathematical diagnostics is the determination of momentary location of the examined system and to forecast of the direction and velocity of its movement in this multidimensional state space. The paper shows theoretical backgrounds and basic methodology of mathematical diagnostic modeling of technical systems.
