It is not working. Giving error about the reshape.

Answer 1

[Azzi Abdelmalek]

There is no such block, but you can call the LQR function from simulink by using Interpreted MATLAB Function

[Ahmed]

Can you send me example

[Joschua]

Did this work for you? I'm trying to do code generation, but an error message appears, telling me that Intepreted MATLAB functions are not supported yet.

Answer 2

[Pawel]

Send me also this example :) I have write an e-mail 2you.

Hi, can I have the example? I'm trying to generate simulink model using LQR, but its a bit confusing.

[Nanu Abel]

Hi Mira, I am doing a final year project on quadrotor and also using the same controller which is LQR. Can you help me with the derivation part and also explain to me on how to implement the controller to the system. Thank you in advance :)

Hi Nanu I am working on design LQR controller for quadrotor and I'm so confused . do u can help me? please connect with me. [e-mail]

There already is example where the LQR is created via blocks in SImulink: https://www.mathworks.com/help/control/getstart/design-an-lqr-servo-controller-in-simulink.html

Type

lqrpilot

for the diagram and

lqrdes

to calculate the LQR gain (or call CTRL+D on the lqrdes to view the code).

If you want to build LQR gain during simulation. You have to use the block in File Exchage: https://www.mathworks.com/matlabcentral/fileexchange/67268-simulink-block-of-lqr as others suggested.
