An Adaptive Grey Fuzzy PID Controller With Variable Prediction Horizon
The concept of grey system theory, which has a certain prediction capability, offers an alternative approach for various kinds of conventional control methods, such as PID control and fuzzy control. For instance, grey PID type fuzzy controller designed in this paper, can predict the future output values of the system accurately. However, the forecasting step-size of the grey controller determin...
متن کاملImprove Fuzzy-PSO PID Controller by Adjusting Transfer Function Parameters
In today‟s world, fuzzy logic and particle swarm optimization are used to answer various engineering problems. In this paper, the proportional integral derivative (PID) controller tuning by fuzzy rule method (FRMs) and a particle swarm optimization (PSO) algorithm are proposed to improve controller by adjusting transfer function parameters. The proposed fuzzy rule function and PSO algorithm sea...
متن کاملStable Adaptive Fuzzy PID Controller for Nonlinear Uncertain Systems
Abstract This paper investigates an improved fuzzy adaptive control scheme for a class of nonlinear uncertain systems. A fuzzy system, whose inputs are the feedback error signals instead of the state variables, is used to cancel the nonlinear function. By using the feedback errors as the inputs of the fuzzy system, the disturbance rejection performance can be achieved because the controller wil...
متن کاملAn optimal fuzzy PID controller
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 only for the design; the resulting control...
متن کاملHybrid Fuzzy Logic Pid Controller
This paper investigates two fuzzy logic PID controllers that use simplified design schemes. Fuzzy logic PD and PI controllers are effective for many control problems but lack the advantages of the fuzzy PID controller. Design methodologies are in their infancy and still somewhat intuitive. Fuzzy controllers use a rule base to describe relationships between the input variables. Implementation of...
