OpenOCL v6 now with acados interface!
Optimal Control allows you to formulate control problems (control theory) as mathematical optimization problems. OpenOCL provides a modeling language that makes it particularly easy to implement optimal control problems in a natural way. The toolbox assures that the optimal control problems can be solved in an efficient way, and is able to directly call the fast (C/C++) implementations of the underlying numerical optimization solvers that calculate the control inputs for your system.
- Model dynamical systems: robot, car, aircraft, spacecraft, wind turbine, mechanical system, chemical system
- Specify cost functions or rewards: balancing of a robot, grasping, reaching goal in minimum time, tracking problems
- Specify constraints: joint limits, obstacles, velocity limits, torque limits, flight envelop, starting state, end state
- Solve the optimal control problem with Ipopt, a powerful non-linear programming solver (non-linear cost, constraints, dynamics)
- Analyze the the behavior of your system for different conditions
- Monte Carlo simulation
Model Predictive Control:
- Solve the optimal control problem in real-time with specialized solvers that take advantage of the problem structure (linear, quadratic, polytopic, non-linear constraints/costs/dynamics)
- Real-time iteration to minimize feedback times in a real-time loop
- Automatic differentiation through CasADi
- Multi-stage problems
- Matrix-valued variables
- Access all variables by their name (no indexing required)
- Easy plotting of initial guess, intermediate steps, and solution
- Get started within minutes (dependencies will be resolved automatically on first startup)
- Get the .mltbx package from the website and install as an Add-on
Applications (non-exhaustive list):
- Aerospace engineering
- Wind power
- Mechanical systems
- Chemical systems

Hi Jan, thanks a lot for the feedback! I updated the description, let me know (here or by mail) if there is anything missing that you would expect to be in the description. Best, Jonas
@Moritz and Jonas: It would be useful to explain here, what this tool does, because this is the information users need to decide, if this is a useful submission for them or not. The link to opencl.org clarifies this exhaustively, if you are familiar with this topic already. But the average visitor on the FileExchange pages won't get any clue. Who needs this tool to solve which problem? Kind regards from Heidelberg!
Easy to use, nice!
feature automatic differentiation
reformulation of description
- allow use of custom CasADi installation
- multi-stage problems (bouncing ball)
