Control system analysis and design via the “second method” of lyapunov: II discrete-time systems

The second method of Lyapunov is applied to the study of discrete-time (sampleddata) systems. With minor variations, the discussion parallels that of the companion paper on continuous-time systems. Theorems are stated in full but motivation, proofs, examples, and so on, are given only when they differ materially from their counterparts in the continuous-time case. © 1960 by ASME.
