How to model in matlab and simulink

[Aquatris]

First you derive the equations that represent the working dynamics of the system. Then, you implement the equation using simulink block diagrams. If you want someone to derive the equations for you, this is not the platform for it.

You could model the system using differential equations and then use MATLAB symbolic math toolbox to solve them. Please find the links below:

Hi Jesus,

One way is to describe the system is using differential equation. Classical text book of dynamic systems can guide you. Then, you can use Simulink to represent this differential equation, where the integrator block is the key block to use, please have a look at this link:
