MataveControl V13.0

MataveControl is a basic toolbox for control engineering. The toolbox can be used for both GNU Octave and MATLAB®. Easy to use and easy to install. The main focus of MataveControl is to offer a control toolbox which can be used in both GNU Octave and MATLAB®. MataveControl has the same function names as MATLAB®'s Control System Toolbox, but the time discrete functions are included in the time continuous functions. Also the library is a very basic library so other developers can fast dive into the code.

TODO

• reg.m This need to be fixed so it is the same as MATLAB
• lqgreg.m I don't know if Matavecontrol should keep it. It do the same as reg.m.
• More work on gensig.m
• Make linprog.m faster by using vectorization and not C-code style
• Make arma.m return a transfer function with discrete time 1
• ARMA models should be simulated with Euler-method, instead of filter.

Typical use

To use MataveControl, you should allways start with to create a transfer function or a state space model. Then you can use that mathematical model in almost all the function of MataveControl.

Here is some examples when I use MataveControl. MATLAB pictures are from Umeå University.

Model Predictive Control - Linear programming & Quadratic programming with integral action

MataveControl have both linear programming MPC and quadratic programming MPC. There is equivalent C code at CControl if you want to apply them to embedded hardware. Select the programming method, quadratic or linear, that works with your situation. Both works fine, but quadratic programming (Hildreth's Method) is faster than linear programming (Simplex Method) in MATLAB. In C-code, it depends on your C-compiler. I have done more work on qmpc.m file, compared to lmpc.m, even if they both can do the same job.

If you want to understand practical and proper MPC without theory, you should:

• Acquire all the math from the thesis Model Predictive Control for an artifical pancreas - Matias Sørensen og Simon Kristiansen.pdf (Download it here at MataveControl)
• Stody the chapters 1 and 2 from Model Predictive Control System Design and Implementation Using MATLAB® by Liuping Wang (Important that must be chapter 1 and 2, ignore the rest of the chapters)
• Throw away your lecture notes/literature from your MPC class, they just wasting your time

Install

To install MataveControl, download the folder "matave" and place it where you want it. Then the following code need to be written inside of the terminal of your MATLAB® or GNU Octave program.

path('path/to/the/folder/matave', path)
savepath

Example of a typical path.

path('C:\Users\dmn\Documents\Octave\matave\', path)
savepath

Update

Write this inside the terminal. Then MataveControl is going to download new .m files to MataveControl from GitHub
