The Control System Designer app is useful for designing single-input, single-output (SISO) controllers for feedback systems modeled in MATLAB or Simulink. Here's an example of designing an LQR controller using the app:
Currently, there's no direct way to generate code for the controller design procedures used by the app. For state-space control design, a list of MATLAB functions can be found here:
However, these functions do not support code generation, as they are not listed on this page, which lists the MATLAB functions that support code generation:
Additionally, the following MATLAB Answers also state that these functions do not support code generation. Staff have mentioned that internal requests have been made to enable this in future releases:

- https://www.mathworks.com/matlabcentral/answers/508844-lqr-and-c2d-not-available-with-matlab-coder
The only workaround mentioned is to write a custom Riccati equation solver. For linear time-invariant (LTI) systems, it's recommended to compute the gain matrix separately and use it directly in the model.
I hope this answers your query!
