Simultin Soldering Station project

Hi,

I prepared a real model of soldering station, it is working properly but for simulations I need a model made in simulink...

So far I have had occasional contact with this tool, this is why I need help.

Can anyone help with this problem? I don't think it's too complicated for someone who knows how to do it in Matlab.

Hi Mateusz Pawlowski,

I understand that you have a physical model of a soldering station that operates correctly, and now you want to create a corresponding simulation model in Simulink.

Assuming you are looking for a basic structure to start with, a typical Simulink model for a soldering station might involve a thermal model for the iron, a control system for temperature regulation, and possibly a user interface to set the desired temperature. You can start by using blocks such as Transfer Functions or State-Space blocks to represent the thermal dynamics, and PID Controller blocks for temperature control.

Here's an example of how you might begin constructing your Simulink model:

1. Open Simulink and Create a New Model: Start MATLAB and open Simulink. Click on "Blank Model" and then "Create Model."
2. Add Input Block: Drag a "Step" block from the "Sources" library. This will act as your desired temperature input.
3. Add Controller Block: Drag a "PID Controller" block from the "Continuous" or "Control Design" library. This will regulate the temperature.
4. Add Plant Block: Drag a "Transfer Function" block from the "Continuous" library. Define the transfer function parameters to model the thermal dynamics of the soldering iron.
5. Add Output Block: Use a "Scope" block from the "Sinks" library to visualize the temperature of the soldering iron over time.
6. Connect the Blocks: Click and drag to connect the blocks in the following order: Step -> PID Controller -> Transfer Function -> Scope.
7. Configure the Blocks: Double-click on each block to set its parameters. For the "Step" block, set the step time and initial value. For the "PID Controller," you may start with default parameters and then tune them. For the "Transfer Function," enter the numerator and denominator coefficients that best represent the thermal behavior of your soldering iron.
8. Run the Simulation: Click on the "Run" button to start the simulation. Observe the response in the "Scope" block.
9. Tune the PID Controller: Use the PID Tuner app in MATLAB by right-clicking on the PID Controller block and selecting "PID Tuner." Adjust the parameters to achieve the desired response.
10. Implement User Interface: If you want to create a user interface to set the desired temperature, you can use the "Dashboard" library in Simulink to add interactive blocks like knobs, switches, and gauges.
11. Validate the Model: Compare the simulation results with your real-world data to validate the model. Adjust the simulation parameters as needed to ensure that the model accurately represents the physical system.

By following the steps you could be able to create a Simulink model for your physical system.

Refer to the documentation of Simulink to get started on creating models and understanding the basics:
