Proportional Integral Integral Control Device and Method Using Fuzzy Inference

摘要

The present invention relates to a powerful proportional integral derivative control apparatus and method using fuzzy reasoning, and more particularly, to a PID control apparatus and method using a fuzzy inference. More specifically, when a proportional integral derivative (PID) control apparatus is difficult to cope with sudden change of the system, The present invention relates to a proportional-integral-derivative control apparatus and method using fuzzy inference, which can cope with a sudden change of the system by appropriately changing the parameters of the apparatus and performing stable control. In other words, the apparatus and method for controlling the PID using the fuzzy inference according to the present invention allow the fuzzy inference controller to control the PID controller through a path different from the closed loop, It is possible to perform powerful control inherent to the PID controller by stopping or operating the fuzzy gain controller according to the degree of error and then performing gain adjustment from the expert's point of view by fuzzy reasoning even if the parameter deviates from a certain level There are advantages to be able to.
