SAM: An Alternative to Sampled-Data Signal Flow Graphs

摘要

This report describes an alternative to the use of Signal Flow Graphs and Mason's Gain Rule for the analysis of complicated digital control systems. The technique is analytical in nature and makes use of a systematic manipulation of algebraic equations describing the system to be analyzed. The technique is modified to be amenable to a new signal flow graph method for the analyst who prefers using signal flow graphs. Both the analytical technique and the modified signal flow graph technique are applied to examples and compared to a standard signal flow graph technique to display their relative advantages. (Author)
