Design And Research On Intelligent PID Control System

PID controller has simple structure and good robustness and it is widely used in process control systems. But conventional PID controller can't get good performance for the time-varying objects and non-linear systems. So several methods of conventional and intelligent PID control are studied systematically and deeply in this paper. Some tasks were finished as listed below:(1)Various form of fuzzy PID controller combinated by fuzzy controller and conventional PID controller are in research based on analysis of conventional PID controller and fuzzy controller.(2)Neural network, BP neural network are also in research in theory. Then PID controller, fuzzy controller and neural network are combinated to be neural network fuzzy PID controller by selflearning.(3)we study the application of PID controller, fuzzy controllers fuzzy PID controller and neural network PID controller in temperature control of laboratory boiler based on AE2000 controller system Using program language, a man-computer interface is designed to switch different...
