Block Diagram Reduction Rules - Control System. We have discussed in our previous article that for the easiness of analysis of a control system, we use block diagram representation of the control system. Basically we know that a complex system is difficult to analyze as various factors are associated with it.

Rules for Block Diagram Reduction. Any complex block diagram representing a system can be reduced to a simple block diagram for determining the transfer function by applying certain rules. The rules that can be used in simplifying the given complex block diagram are as explained below. Proof for the rules is obtained by determining the output ...

(s), using block-diagram reduction rules. Task 2: Develop a Simulink model for the original system in Figure 8. Set the reference signal input, r v (t)=4 u(t), as a step input with a zero initial value, a step time= 0 seconds, and a final value of 4 volts. Use X-Y graphs to display (over the period from 0 to 8 seconds)
