MatLab之Simulink之simple model

　　

　　Use Simulink to model a system and then simulate the dynamic behavior of that system.

　　　　

 

1　　Open

　　in Command Window, type simulink, open Simulink Library Browser

2　　Create model

　　File -> New -> Model, and then save it.

3　　Add blocks

　　add following blocks from Simulink Library Brower (Ctrl + I)

• Sine Wave — Generates an input signal for the model

• Integrator — Processes the input signal

• Bus Creator — Combines the input signal and processed signal into one signal

• Scope — Visualizes the signals

4　　Connection

　　connect them with lines, Ctrl + click is useful when connecting widely separated blocks or when working with complex models

 

5　　Simulation parameters

　　Simulation -> Model Configuration Parameters, then Solver -> Stop time(20), Solver -> max step size(0.2)

　　  

6　　Run and observe

　　Simulation -> Run, afte simulation we can view results by double-click the Scope block.

　　In Scope toolbar, click Parameters button . Select the Style tab and edit figure parameters properties.
