Control System. The closed-loop control system example is shown below. For the above system, C(S) = E(S) * G(S) E(S) = R(S) H(S) * C(S) Substitute this E(S) value in C(S), then we can get. C(S) = [R(S) H(S) * C(S)]* G(S) C(S) = R(S) G(S) H(S) * C(S) * G(S) From the above equation. R(S) G(S) = C(S) + H(S) * C(S) * G(S)
Basic Elements 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).
A block diagram representation in which there is only one forward and feedback block along with a single summing point and take-off point is the simplest form of closed-loop control system. It is also known as the canonical form of a closed-loop system. The figure below shows a simple closed-loop system: Example of Control System. Let us take

(b) Practical Closed Loop System: An automatic toaster with feedback is taken as an example of the practical closed loop control system. The block diagram is shown in Figure. The input of the system is desired quality of the toast. The output of the system is the actual quality of the toast.
Jul 17, 2015· The block diagram of the closed loop system is shown below. As these systems contain feedback loop, the closed loop control systems are also called as “Feedback control systems”. By giving the feedback to the input signal, we can accurately control the output of a control system. A closed loop control system can have more than one feedback
