Difference between Transfer Function and State Space Analysis

State space analysis and transfer function are two different representations used in control system engineering to describe and analyze the behavior of dynamic systems. Transfer Function Definition: Transfer Function: A transfer function is a mathematical representation that describes the relationship between the input and output of a linear time-invariant (LTI) system in the frequency domain. […]

Control Systems

By frequency domain analysis, we mean the steady state response of a system when subjected to a sinusoidal input. In frequency domain methods, the frequency of the input signal is varied over a certain range and study the resulting response. This is shown in Figure 1. Figure 1: System subjected to different frequencies Frequency domain

Signal Flow Graph (SFG)

Leave a Comment / Control Systems

Signal Flow Graph (SFG) is an Alternative method to block diagram representation. Like block diagrams it does not consist of blocks, summing points and take-off points. It only of a network in which nodes are connected by directed branches. Definition: A signal flow graph is graphical representation of the relationship between variables of set of

Transfer Function

Leave a Comment / Control Systems

Transfer Function is the ratio of Laplace transform of the output to the Laplace transform of the input, assuming all initial conditions zero. In general Where x is the input of the system and y is the output of the system. When order of the denominator polynomial is greater than the numerator polynomial the transfer

System The word “Control System” has two separate words. First one is “Control” and next is “System”. Let us see, what is a System? Definition: A system is a collection of elements or components which act together as an entire unit to achieve certain objective. For example: A Classroom has desks, benches, board and students etc those
