A design and simulation of fuzzy PID controller for the optimization of temperature and humidity in the thermodynamic system

摘要

The article describes modern methods of controlling for the optimization of continuous technological processes. Naturally, it is necessary to make provision for the level of technologies, which in recent times make use of the modern means of controlling. Characteristic feature of all of them is partial to complete decentralization of controlling from simple, two-level controlling, up to the fully decentralized controlling using LON (Local Operating Network) technologies. However, in all of them the common feature is the existence of a dispatcher (superior) level serving for the monitoring of technology, or for its optimization in the form of interventions of men into the control. By using the superior level for controlling we thus practically create an adaptive system capable of bringing the behavior of all the control system in line with the current state of the technological process, while preserving the process level of controlling.
