A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams. When applying this equation, it is best to construct a free-body diagram (FBD) of the sysetm showing all of the applied forces. Example: Mass-Spring-Damper System. The free-body diagram for this system is shown below.

22.451 Dynamic Systems – Block Diagrams Example - Block Diagram Representation Next, replace the parallel combination by the previous configuration to obtain what appears as a series combination of two blocks. Since this is a series combination, the equivalent transfer function is simply the product of the individual transfer functions. 5 2 3 ... Figure 8.16 Moving summation function past blocks Recall the example of a cruise control system for an automobile presented in Fig-ure 8.4. This example is extended in Figure 8.17 to include mathematical models for each of the function blocks. This block diagram is first simplified by multiplying the blocks in sequence. called the block diagram. This section first explains what a block diagram is. Next, it discusses introductory aspects of automatic control systems, including various control actions.Then,it presents a method for obtaining block diagrams for physical systems,and, finally, discusses techniques to simplify such diagrams. Block Diagrams. Signal flow graph is used to represent the control system graphically and it was developed by S.J.Mason. Signal flow graph is a diagram that represents a set of simultaneous linear algebraic equations.By differential equations governing a control system can be algebraic equations in s-domain.The signal flow graph of the system can be constructed using these equations. Block Diagram Reduction Rules DEFINITION: A block diagram of a system is a pictorial representation of the functions performed by each component of the system and shows the flow of signals. In block diagram, the system consists of so many components. These components are linked together to perform a particular function.
