Use tf to create real-valued or complex-valued transfer function models, or to convert dynamic system models to transfer function form. Transfer functions are a frequency-domain representation of linear time-invariant systems.

Create Transfer Function Using Numerator and Denominator Coefficients. This example shows how to create continuous-time single-input, single-output (SISO) transfer functions from their numerator and denominator coefficients using tf. Create the transfer function G (s) = …

Jan 2, 2020 · We like to design systems with s-domain transfer functions, but often we need to implement the final solution in software. This video describes how to go from a transfer function to code that can run on a microcontroller.

Apr 14, 2015 · This video demonstrates how you can create a transfer function to model a linear-time invariant system. Two transfer functions are combined to create a plant model. You can add a controller, and compute the closed-loop transfer function.

[b,a] = ss2tf(A,B,C,D) converts a state-space representation of a system into an equivalent transfer function. ss2tf returns the Laplace-transform transfer function for continuous-time systems and the Z-transform transfer function for discrete-time systems.

Jan 6, 2014 · Create a linear system. For this example, create a third-order transfer function.

Estimate and plot the frequency-domain transfer functions of the system using the system data and the function tfestimate. Select the "mimo" option to produce all four transfer functions.

tf2ss converts the parameters of a transfer function representation of a given system to those of an equivalent state-space representation. For discrete-time systems, the state-space matrices relate the state vector x , the input u , and the output y :

Use tf2zp when working with positive powers (s 2 + s + 1), such as in continuous-time transfer functions. A similar function, tf2zpk, is more useful when working with transfer functions expressed in inverse powers (1 + z –1 + z –2).

A transfer function describes the relationship between input and output in Laplace (frequency) domain. Specifically, it is defined as the Laplace transform of the response (output) of a system with zero initial conditions to an impulse input.
