Control systems need to react to the environment in a predicable and repeatable fashion. Control systems take measurements and use them to control the process. For example, a ship measures its heading and changes its rudder angle to attain that heading.
Typically, control systems are designed and implemented with all of the parameters hard coded into the software. This works very well in most circumstances, particularly when the system is well known during the design process. When the system is not well defined, or is expected to change ...
