A system in which input has a command over the output or a system in which input has a control over the output is called a control system. A water tap can be taken as simple and best example of a control system. Here the flow of water (i.e., the output) is mechanically controlled by the movement of valve (i.e., input). The diagrammatic representation of simple control system is shown below Continue reading What is Control System? Theory, Diagram, Elements & Examples

Block Diagram in Control System – Reduction Rules, Procedure & Properties
Block diagram is a pictorial representation of a control sytem. Each element is represented by a separate block and each block is characterised by transfer function of the element. Let us consider element of a control system having transfer function G(s). If the input and output of element are X(s) and Y(s) respectively, then this element is represented by a block as shown in Fig. 1.

Comparison between Open loop and Closed loop control systems
After reading this topic Comparison between Open loop and Closed loop control systems, you will understand the theory and comparison.
Open loop control systems
It is a control system in which the control action independent of the output signal and depends only on its input signal, also the signal flows through the block is unidirectional. It is shown below,

Closed loop or feedback control systems
After reading this topic Closed loop or feedback control system, you will understand the theory, examples, advantages, disadvantages, and comparison.
It is a control system in which the control action dependents on both the output signal and the input signal. It is shown below in Figure 1.
