Control and set the desired frequency in activ filters using fuzzy PID controller

The design and tuning of PID controller coefficients by fuzzy logic, a similar approach to adaptive controllers, based on the ability of fuzzy systems to infer, has been proposed at any time of the day for specially proposed PID controller coefficients. This approach is a Gain Scheduling task, which is responsible for determining the interest rates for a fuzzy system. This fuzzy system calculates the values of the PID controller coefficients appropriately and fits into the controller structure by receiving the error and the derivative of the error at any given time. Of course, as we write Fuzzy_PID, this does not mean that this is the only way to design a PID controller fuzzily, or to combine the control theory and the fuzzy theory to implement a PID controller, just the method outlined here. In this study, we will examine the frequency control of an active filter (eg low pass active filter) and compare the control, PID, fuzzy and PID-Fuzzy methods (fuzzy control PID controller coefficients).
