An optimal fuzzy PID controller

IEEE Transactions on Industrial Electronics, 2001
This paper introduces an optimal fuzzy proportional-integral-derivative (PID) controller. The fuzzy PID controller is a discrete-time version of the conventional PID controller, which preserves the same linear structure of the proportional, integral, and derivative parts but has constant coefficient yet self-tuned control gains. Fuzzy logic is employed

Fuzzy anti-reset windup for PID controllers

Control Engineering Practice, 1993
Abstract In this paper anti windup schemes for PID controllers are proposed that consider not only actuator constraints but also process state constraints. The schemes are fuzzy generalizations and combinations of the traditional conditional integration anti windup schemes.

Flexible complexity reduced PID-like fuzzy controllers

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2000
In this paper, a flexible complexity reduced design approach for PID-like fuzzy controllers is proposed. With the linear combination of input variables as a new input variable, the complexity of the fuzzy mechanism of PID-like fuzzy controllers is significantly reduced.

Two-level tuning of fuzzy PID controllers

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2001
Fuzzy PID tuning requires two stages of tuning; low level tuning followed by high level tuning. At the higher level, a nonlinear tuning is performed to determine the nonlinear characteristics of the fuzzy output. At the lower level, a linear tuning is performed to determine the linear characteristics of the fuzzy output for achieving overall ...

Developments of fuzzy PID controllers

Expert Systems, 2005
Abstract: This paper describes the development and tuning methods for a novel self-organizing fuzzy proportional integral derivative (PID) controller. Before applying fuzzy logic, the PID gains are tuned using a conventional tuning method. At supervisory level, fuzzy logic readjusts the PID gains online.

Intelligent Fuzzy PID Controller

2008
This chapter aims to describe the development and two tuning methods for a self-organising fuzzy PID controller. Before application of fuzzy logic, the PID gains are tuned by conventional tuning methods. In the first tuning method, fuzzy logic at the supervisory level readjusts the three PID gains during the system operation.

Fuzzy PID Control of Microgrids

2019
The purpose of this chapter is design and application of intelligent methods based on the fuzzy logic (FL) type PID controller for adaptive controlling of the microgrids. The traditional structure of the power systems is being changed continuously due to environmental limitations and depreciated infrastructures.

Discrete-Time Fuzzy PID Control

2015
In this study, a parallel structure of fuzzy PID control systems is presented. It is associated with a new tuning method which, based on gain margin and phase margin specifications, determines the parameters of the fuzzy PID controller. In comparison with conventional PID controllers, the presented fuzzy PID controller shows higher control gains when ...

Design of equivalent fuzzy PID controller from the conventional PID controller

2015 International Conference on Control, Instrumentation, Communication and Computational Technologies (ICCICCT), 2015
Fuzzy controllers are nonlinear and it is more difficult to set the controller gains when compared to conventional controllers. This research paper proposes a design procedure for equivalent fuzzy PID controller from the conventional PID controller domain over to single loop speed control of DC motor.
