Learn about MATLAB support for nonlinear model. Resources include code examples, videos, and documentation describing different nonlinear models.

In this control engineering tutorial, we explain how to linearize models of nonlinear dynamical systems in Simulink and how to export the linearized models to the MATLAB workspace.

Building the nonlinear model with Simulink We can build the inverted pendulum model in Simulink employing the equations derived above by following the steps given below.

I have a set of non-linear equations, which I would like to model in Simulink in order to compare to their linear counterpart. Here is the block diagram of my setup.

Although you specify which Simulink blocks to linearize, all blocks in the model affect the operating point. A nonlinear model can have two very different linear approximations when you linearize about …

Using Nonlinear ARX Models Simulate, predict, and forecast model output, linearize nonlinear ARX models, and import estimated models into the Simulink ® software. Linear Approximation of …

This paper provides an introduction to Simulink for the simulation analysis of nonlinear systems. It covers essential tools and techniques for modeling, simulating, and linearizing nonlinear systems …

Use nonlinear model identification when a linear model does not completely capture your system dynamics. You can identify nonlinear models in the System Identification app or at the command line.

Nonlinear Elements Modeling Modeling piecewise linear nonlinearities The one-dimensional “Look-up Table” block can be used to represent piecewise-linear nonlinearities

The Nonlinear ARX Model block simulates the output of a nonlinear ARX model using time-domain input data.
