MPC: multiprecision C library for arithmetic of complex numbers

Mpc is a C library for the arithmetic of complex numbers with arbitrarily high precision and correct rounding of the result. It is built upon and follows the same principles as Mpfr. The library is written by Andreas Enge, Philippe Théveny, Paul Zimmermann and Mickaël Gastineau and is distributed under the Gnu Lesser General Public License.

Gekko MPC controller - update parameters at each time step

I am working on an MPC problem with individual linear models predicting the control variable at each time step in the prediction horizon (see below where u is the manipulated variable and y is the control variable). The coefficients of each linear…

There is a real reason for gcc to be so conservative with its dependecies ? ( MPFR, GMP, MPC )

I'm wondering if someone knows why gcc tends to be so conservative about the versions of the libraries to use to compile and build gcc itself . The main reasons why I'm asking this are : I think that there is a big shift between the "implicitly…

Is it possible to use this gekko MPC method online on a real robot?

I want to do some trajectory tracking on a real robot, and I want to use MPC, so I found this gekko. I can make to simulations of my robot and stuff, but is it possible to use it real-time, as I see it take some time to calculate the optimal…
