The most common technique used for modeling linear, time-invariant systems is the block diagram, with the mathematical model represented as a transfer function. As an example of the first situation - ...

Block diagrams and signal-flow graphs are used to represent and to obtain the transfer function of interconnected systems. The reduction of signal-flow graphs is considered simpler than the reduction ...

With the help of the block diagram reduction approach, we discuss the stability analysis in the S domain using the RH stability criterion for a different closed-loop control system. Comparison of ...
