Three Tank Control System on Simulink

[zyho]

I am doing Control on Three Tank System using Simulink and I am newbie in Simulink. I am having a problem in the Simulation of Simulink. I am having the equation as below:

az1×Sn×sign(h1-h2)√(2g|h1-h2|)

where
az1, Sn and g is constant.
h1 and h2 is the input of the system.

This equation is the subsystem of one block.

To do it in Simulink, I can actually represent the equation with each block. I am having some difficulties on finding the correct blocks.

Is there any way to do it? Possibly using function block to run the equation?

Please Advice.

Hi there,

Thank you for sharing your project on the three tank system using Simulink. It sounds like you are facing some challenges in simulating your system and representing the equation in Simulink.

Firstly, let me assure you that Simulink is a powerful tool for simulating and modeling dynamic systems, and with some practice, you will be able to represent your equation accurately. Here are some tips that may help you in finding the correct blocks for your equation:

1. Break down your equation into smaller parts: Since your equation is a combination of different variables and operations, it would be helpful to break it down into smaller parts. This will make it easier for you to identify which blocks are needed for each part.

2. Use Simulink's built-in blocks: Simulink offers a wide range of built-in blocks that can perform various mathematical operations, such as multiplication, division, square root, etc. You can use these blocks to represent the different parts of your equation.

3. Consider using the "Function" block: The "Function" block in Simulink allows you to define custom functions using MATLAB code. You can use this block to write the code for your equation and then use it in your simulation.

4. Look for similar examples: Simulink has a vast library of examples that you can refer to for inspiration and guidance. You can search for examples related to your project or equations similar to yours and see how they have been implemented in Simulink.

I hope these tips will help you in representing your equation accurately in Simulink. Remember, practice makes perfect, so don't get discouraged if it takes some time to get it right. Also, don't hesitate to reach out to the Simulink community for support and advice.

Best of luck with your project!
