Questions tagged [transfer-function]

A transfer function is a mathematical description of a system or part of a system. It relates the output of the system to the input. The system described by a transfer function is always linear and time invariant.

A transfer function is a mathematical description of a system or part of a system. It relates the output of the system to the input. The system described by a transfer function is always linear and time invariant.

Transfer functions are appropriate for single input single output systems; while several can be used to model a multiple input multiple output system it is usually more appropriate to use a state space representation in that case.

Common uses of transfer functions are;

  • Single-input single-output filters
  • Modelling systems for control theory

Constructing a transfer function

How would I go about creating the below transfer function? It would take two parameters: position of bulge in range (-1.0, +1.0) sharpness of bump That picture only demonstrates movement in the first parameter. I can think of a few possible…

What does "matscale" function in Matlab actually do?

I'm trying to implement a convertor from z to s time for transfer function in Python. Matlab give us an opportunity to do this using d2c function. But i can't get what the "matscale" function does. I've stucked in mscale.m file with calling…

Matlab - find dominant poles programmatically

I have a SISO system (in tf form) with 48 eigenvalues and I want to find the dominant poles (let's say to reduce it to a 1st or 2nd order). I need to know them to approximately calculate damping and bandwidth of my system. I would like not to rely…

Matlab get transfer function from Simulink

Is it possible to use MATLAB to retrieve the data from Simulink from this block diagram and plot the transfer function? I have already tried using tf, but that did not work. res = sim("Test.slx"); G = tf(res.simout.data,res.in.data);
