Obtain a Linear Parameter Varying (LPV) approximation of a Simscape™ Electrical™ Power Systems model of a Boost Converter. The LPV representation allows quick analysis of average
Plot linearization of a Simulink model at particular conditions during simulation. The Simulink Control Design software provides blocks that you can add to Simulink models to compute and
Specify the rate conversion method for the linearization of a multirate model. The choice of rate conversion methodology can affect the resulting linearized model. This example
Use the time based operating point snapshot feature in Simulink Control Design. This example uses a model of the dynamics of filling a cylinder with compressed air.
The process that the command linearize uses when extracting a linear model of a nonlinear multirate Simulink model. To illustrate the concepts, the process is first performed using
Specify the linearization of a Simulink block or subsystem.
Use the slLinearizer interface to batch linearize a Simulink model. You vary model parameter values and obtain multiple open- and closed-loop transfer functions from the model.
Specify the linearization for a model component that does not linearize well using a linear model identified using the System Identification Toolbox™. This example requires Simscape™
Trim and linearize an airframe. We first need to find the elevator deflection and the resulting trimmed body rate (q) that will generate a given incidence value when the airframe is traveling
Use the command LINEARIZE to speed up the batch linearization where a set of block parameters are varied.
The features available in Simulink Control Design for linearizing models containing references to other models with a Model block.
Approximate the nonlinear behavior of a system as an array of interconnected LTI models.
Use the slLinearizer interface to batch linearize a Simulink® model. You linearize a model at multiple operating points and obtain multiple open-loop and closed-loop transfer functions
Use the linearize command to batch linearize a model at varying operating points.
In this example, you vary model parameters and linearize a model at its nominal operating conditions using the linearize command.
Use the slLinearizer interface to batch linearize a Simulink® model. You vary model parameter values and obtain multiple open-loop and closed-loop transfer functions from the model.
If your application includes parameter variations that affect the operating point of the model, you must batch trim the model for the parameter variations before linearization. Use this
Compute a linear model of the combined controller-plant system without the effects of the feedback signal. You can analyze the resulting linear model using, for example, a Bode plot.
