Transient response improvement of PID controller using ANFIS-hybrid reference control

Abstract

The standard PID controller is known to have performance limitations as it must trade off the transient response performance and the disturbance attenuation level. The paper presents a hybrid reference control (HRC) with adaptive neuro-fuzzy inference system (ANFIS) to improve transient response performances of a stabilized closed loop system using PID controller. The ANFIS is used to manipulate the set-point of the PID controller in a specific manner such that the transient response is improved. As a result, the transient response performances and the disturbance attenuation can be designed independently.
