PSO in simulink

Hi. I want to run PSO algorithm in Simulink with s-functions.I will do optimization of control system with PSO. Could you help me? You can suggest anathor way for this. Thank you very much.

[Guy Rouleau]

By PSO, I assume you mean the Pittsburgh Symphony Orchestra?

[Seth Popinchalk]

In general, optimization is applied to a Simulink model using MATLAB commands to adjust variables that define the parameters of the simulation. Using Particle Swarm Optimization (PSO) to optimize a system modeled in Simulink can use the same approach. Define the system you would like to optimize in Simulink and some measurement of quality of the solution based on the outputs of the simulation. Use MATLAB workspace variables to define the parameters of the system that are changing, including initial conditions or input signals to the model. The simulation can be run using the sim command to generate the outputs of the model.

Using a PSO Algorithm initialize the particles using random positions in your solution space. Run a simulation for each particle so you can calculate the quality measure. Update the particles best known position if you have improved this measure of quality.

Each particle solution can be run in parallel by running the sim command within a parfor loop.

thank you very much. I will try your suggestion.

This method works but s-function implementation has more advantages: http://www.sciencedirect.com/science/article/pii/S0038092X12001247

Seth Popinchalk - Is it really possible to implement Partcile Swarm Optimization algorithm for online optimization rather than offline optimization?

My idea was to perform this PSO algorithm using an Embedded Matlab Function block inside a simulink model.

hello

[izza anshory]

good, how this algorithm combine with another algorithm, such as bat algorithm ?

Hello dear friend, i see your file i seem a very helpful but i don not know how could you connect the PSO.m file to the simulink can you explain the steps for doing this . my e-mail is [e-mail] shall we connect plz.

[Quan Zhou]

this is an offline optimisation, the connection among m-file and Simulink is in the tracklsq.m file. hope this would help. In addition, have you find any online demo using PSO controller in the loop.

Have a look at this paper. It explains pso implementation as an s-function: http://www.sciencedirect.com/science/article/pii/S0038092X12001247

Dear Seth;

Nice sharing, I also tried the same thing as your suggested above. However it is still limited for real-time implementation such as for xPC target. Is there have any WAY that suitable for real-time implementation for PSO?

Thanks

Addie
