ANALYSIS OF TIME VARYING SYSTEMS USING TIME VARYING S-TRANSFORMS AND TIME VARYING Z-TRANSFORMS

摘要

This paper deals with the analysis of continuous and discrete time varying systems using two unusual representations. These representations, based on time varying s-transtbrm and time-varying z-transform notions, prove to be highly efficient in the field of automatic control. They also permit the extension of many well known theorems to time varying systems such as the initial and final value theorems.
