10. Decoupling
MIMO systems are difficult to control directly by trial and error, as a change in a single input can affect many, if not all, outputs. It would be much simpler if each input (or block of inputs) influenced only one output (or block of outputs). Separating a system into independent subsystems is called decoupling. There are several types of decoupling, depending on the form of the transfer function.
Let's consider, for a square system with the same number of inputs and outputs (p = m), the case of diagonal decoupling, which consists in making the matrix G diagonal. In this case, output i will only be influenced by input i. If G is singular, the system's outputs are not linearly independent. If G is singular, the system's outputs are not linearly independent and it will be impossible to make it diagonally decoupled, whatever the form of control.

Software
There are many different types of control software. Many of them are specific to a certain application, a certain field, such as the aerospace industry. Most of them are commercial and therefore not free.
The most widely used software packages are MATLAB → with a large number of toolboxes covering the majority of design, simulation and implementation methods...
