13. Effects of finite precision
In practice, calculations are carried out with finite precision, and each operation is subject to an error due to the arithmetic of the computer used. The accumulation of such errors can distort the results obtained, sometimes extremely significantly. It is therefore essential to analyze these errors either theoretically, by giving them an upper limit (which is often pessimistic), or by studying them statistically
Consider, for example, the transfer function :

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...
