GRAMPC is a nonlinear MPC framework that is suitable for dynamical systems with sampling times in the (sub)millisecond range and that allows for an efficient implementation on embedded hardware. The algorithm is based on an augmented Lagrangian formulation with a tailored gradient method for the inner minimization problem. GRAMPC is implemented in plain C with an additional interface to C++ and MATLAB/Simulink. The basic structure and usage of GRAMPC are described in the documentation that comes along with the source files. More details about the algorithm and its performance can be found in the corresponding article published in Optimization and Engeneering. The article is available online under open access at: https://doi.org/10.1007/s11081-018-9417-2. Please cite the paper when you are using results obtained with GRAMPC.

Set of tools for algebraic derivative estimation, based on the work of Fliess and its collaborators.

The SPHERES simulation is designed to support most software-related aspects of single- and multi-satellite SPHERES operations. The simulation code base consists of simulated versions of most of the SPHERES core flight code and additional code that simulates dynamics, communications, and other environmental interaction. The simulation is particularly valuable during the early stages of algorithm development and implementation as an aid in accelerating the learning curve for any Guest Scientist for SPHERES. Algorithms may be implemented in C or Embedded MATLAB and executed in the MATLAB simulation environment to verify general desired behavior. With some limitations, the code used in the simulation can be directly transferred to the SPHERES hardware. We are sharing this project with the public to gather more interest for SPHERES Guest Scientists. Feel free to use and contribute to this code base, just don't forget to credit the MIT Space Systems Lab if you distribute any results.

Linux ERT target controls code generation from Simulink for computer based on MPC5200 and Linux. The target contains support for CANopen via Simulink blockset which integrates the CANopen driver to the generated code.
