Calculating Gain and Phase in Matlab 12 • Matlab uses transfer functions to calculate gain and phase and generate bode plots • Recall that there are 2 ways to plot data logarithmically – 1) Plot on a log scale – 2) Take the log of the data & plot on normal scale – Matlab does both (just to be annoying or to
Example 1 Simulating a first order process Consider the following first order ODE model ???? ???? +????=???????? (1) Assuming zero initial conditions the transfer function from input to output ???? is given by ????=(???????? ???? +1) (2) and the transfer function is given by ????????( )=(???????? ???? +1) (3)
In this lab we will first learn how to implement transfer function in both Matlab and in Simulink Next we show how to write block diagrams as signal flow graphs and lastly we will use the signal flow graphs in conjunction with Mason’s rule to determine the overall transfer function of a system
The transfer function can thus be viewed as a generalization of the concept of gain Notice the symmetry between yand u The inverse system is obtained by reversing the roles of input and output The transfer function of the system is b(s) a(s) and the inverse system has the transfer function a(s) b(s) The roots of a(s) are called poles of the
An easy way to create a transfer function in MATLAB involves using the command to create s as a variable and then use s in a line of code to make a transfer function.
The key advantage of transfer functions is that they allow engineers to use simple algebraic equations instead of complex differential equations for analyzing and designing systems.

You can create a transfer function model object either by specifying its coefficients directly, or by converting a model of another type (such as a state-space model ss) to transfer-function form. For more information, see Transfer Functions.
In engineering, a transfer function (also known as system function [1] or network function) of a system, sub-system, or component is a mathematical function that theoretically models the system's output for each possible input. [2] [3] [4] They are widely used in electronics and control systems.
