1. The problem of control
A system is a set of components (mechanical, electrical, biological, etc.) interconnected to perform a certain function. If its behavior varies over time, we speak of a dynamic system. A system has input and output variables. The latter can be measured. The input variables can influence the system's evolution, i.e. the output variables. When they can be voluntarily modified, they are called control variables. Independently of these variables, the system may have internal variables that cannot be accessed; these are called state variables.
Definition 1 – Controlling a system consists in acting on the input variables (control variables) so that the output variables have the desired characteristics.
Controlling a system on the basis of measurements made on output variables is called feedback. It requires...

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...
