A Level-2 MATLAB S-function is a Simulink block that can be used to implement custom, nonlinear models in Simulink. It is Level-2 because it provides more advanced capabilities than a Level-1 S-function, including the ability to store state information and handle continuous-time signals.
To create a Level-2 MATLAB S-function, you need to define the following functions:
1. mdlInitializeSizes: This function is called once at the start of simulation to set up the block's input and output ports.
2. mdlInitializeConditions: This function is called once at the start of simulation to initialize the block's states.
3. mdlOutputs: This function is called at each simulation time step to compute the block's output.
4. mdlUpdate: This function is called at each simulation time step to update the block's states.
5. mdlTerminate: This function is called once at the end of simulation to clean up any resources used by the block.
In addition to these functions, you may also need to define other functions depending on the specific requirements of your model.
Once you have defined your S-function, you can use it in a Simulink model just like any other block. You can also customize the block's parameters and properties to suit your needs.
