Feedback Systems

A block diagram of a negative feedback system is shown in Figure 20.1. The overall system input-output transfer function T(s) is T ( s ) = C ( s ) R ( s ) = G ( s ) 1 + G H ( s ) https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203743102/9cca8f32-4688-4a1e-80c2-a6c9068f5153/content/eq736.tif"/> Figure 20.1 A negative feedback system. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203743102/9cca8f32-4688-4a1e-80c2-a6c9068f5153/content/fig20_1.tif"/>
