Problem with designing MPC

I created an MPC block and try to use the 'Design option'. I put into field some MPC name and click 'Design'. An error appears: 'Specified MPC object 'name' cannot be found in base workspace.

What to do?

Hi @Marcin Pilzak

Because you need to have the MPC object in the Workspace. And this is how you create a basic one:

Plant = tf([1], [1 0 0]);	% double integrator
Ts = 1;                     % sample time
b1 = 3.60e-05;              % upper bound of manipulated variable (MV)
b2 = 4.32e-07;              % upper bound of MV rate
% bounds on the controller
MV = struct('Min', -b1, 'Max', b1, 'RateMin', -b2, 'RateMax', b2);
Np = 300;                   % prediction horizon	
Nc = 0.01*Np;               % control horizon
MPCobj = mpc(Plant, Ts, Np, Nc, [], MV)

Then, you can click on the "Design" button to launch the MPC Designer App.

Hope this info is helpful to you.
