Originální abstrakt

A linear discrete-time system is asymptotically stable, if the poles of the transfer function or the characteristic equation are located inside the unit circle. If single poles are located on the unit circle, then the system is critically stable. For multiple poles on the unit circle, however, it becomes unstable. Four methods for stability analysis of discrete control systems are introduced in this contribution: - algebraic stability criterion; - frequency methods; - root locus methods; - stability analysis through bilinear transformation. Since stability analysis of discrete control systems is difficult task in engineering practice, this article gives understandable explanation.
