GRAMPC / Blog: Recent posts

Major changes:

• Added grampc.param as an additional input for the probfct signatures
  • In addition the parameter ordering of dfdx_vec, dfdu_vec, dfdp_vec and dHdxdt changed
  • xdes and udes are no longer passed to the cost functions as they are available inside grampc.param
• The explicit time dependency of the system dynamics was removed. The dynamics are now called with the MPC internal time. If the global time is needed, one can access t0 in the grampc.param struct
• Added support for discrete-time systems
• Added config reader which reads a .cfg file for GRAMPC parameters and options
• Added CMakeLists.txt files for the GRAMPC library and every example
• Added online documentation
• Added gradient checker and an utility function via finite-differences for computing the gradients in the probfct
• Added Python interface... read more

- Switch from GNU Lesser General Public License (LGPL) to BSD-3-Clause License, see LICENSE.txt
- Support for fixed-size arrays instead of dynamic memory allocation, see Section 5.1.5 in documentation
- Added userparam as additional input to Simulink models
and some minor changes and bugfixes, see CHANGELOG.txt

Hello there,

A new version of GRAMPC (GRAMPC 2.1) is available. It includes many minor improvments, such as dimensions checks in the mex interface and improved plot functions. In addition, the documentation has been improved and extended.

Cheers,

Hello there,

The new version of GRAMPC (GRAMPC 2.0) is available. It is a fundamental revision of the previous version, which takes nonlinear state and input constraints into account. A C++ interface has been added and the Simulink interface optimized to support MATLAB code generation. Furthermore, GRAMPC can now also be used for moving horizon estimation. In addition, many minor improvements are waiting for you.... read more
