How to use model predictive control and quadprog() in MicroAutobox III

I use Matlab2018b to build MPC function in Simulink, but there's an error Function 'quadprog' not supported for code generation and quadprog() can not work in AutoboxIII. Does it work that I update Matlab to 2022a? If not, what might be the possible solutions?

Hi Zekun Yang,

Quadprog does support Code Generation but there are some constraints and limitations for that, go through the following to make sure you are not violating any of them: Quadratic programming - MATLAB quadprog (mathworks.com).

Here is an example for useing code generation for quadprog: Generate Code for quadprog - MATLAB & Simulink (mathworks.com)

Hope this resolves your issue!

Is that possible to work in AutoboxIII?

Hi,

You can use quadprog for simulation and code generation as a solver in Model Predictive Control Toolbox as of R2021b release (see here). So if you upgrade you should be all set. By the way, Model Predictive Control Toolbox also has other built-in QP solvers you can try as you see fit (see here).

Hope this helps
