What are the basic components of block diagram?
The basic elements of a block diagram are a block, the summing point and the take-off point. Let us consider the block diagram of a closed loop control system as shown in the following figure to identify these elements. The above block diagram consists of two blocks having transfer functions G(s) and H(s).
What is a physical block diagram?
The physical block diagram is a traditional systems engineering block-and-line diagram representing the physical links that connect components within a system or system segment. Part of the physical architecture representation set, the physical block diagram is the more detailed view of the architecture composition.
What are the rules for reducing a block diagram?
However, while reducing the block diagram it is to be kept in mind that the output of the system must not be altered and the feedback should not be disturbed. So, to reduce the block diagram, proper logic must be used. Hence for the reduction of a complicated block diagram into a simple one, a certain set of rules must be applied.
How to reduce the size of a block?
Step 1 − Use Rule 1 for blocks G 1 and G 2. Use Rule 2 for blocks G 3 and G 4. The modified block diagram is shown in the following figure. Step 2 − Use Rule 3 for blocks G 1 G 2 and H 1. Use Rule 4 for shifting take-off point after the block G 5. The modified block diagram is shown in the following figure.
Can a complex diagram be reduced to a simple form?
So, such a complex diagram must be reduced to its simple or canonical form. However, while reducing the block diagram it is to be kept in mind that the output of the system must not be altered and the feedback should not be disturbed.
How to calculate the transfer function of a block diagram?
1 Step 1 − Find the transfer function of block diagram by considering one input at a time and make the remaining inputs as… 2 Step 2 − Repeat step 1 for remaining inputs. 3 Step 3 − Get the overall transfer function by adding all those transfer functions. More
