The System Block Diagram Reduction Characteristics Test with Shifting the Node States

To represent the more complicated system into more simplified form and to interpret different physical and mechanical systems we need a block diagram representation technique. The Routh-Hurwitz criterion is a very important and easiest way to find the stability of the Linear Control System in which we compute the number of right half and left-half plane roots. In this paper, we are analyzing the effect of system stability behaviour by node shifting for which we are using the block diagram reduction technique. 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 different Transfer Function characteristics of the control system is done to study their system stability behaviour for which MATLAB simulation results are used for evaluation of objective of this paper.
