Hello, I'm using the Nonlinear MPC on Simulink. Why I get the error: All entries of input All entries of input Slack0 must be nonnegative. must be nonnegative. I have tried to change the weight on the slack variable (in the cost function), but this doesn't always work. Thank you

Hello,

I'm using the Nonlinear MPC on Simulink.

Why I get the error:

All entries of input All entries of input Slack0 must be nonnegative. must be nonnegative.

I have tried to change the weight on the slack variable ε (in the cost function), but this doesn't always work.

Thank you

Hi,

I have same problem in Nonlinear MPC, Could you please share how to define the slack variable in Constraint function ?
