Design and Implementation of the PI-type Active Disturbance Rejection Generalized Predictive Control

Abstract

In order to overcome the limitations of the Active Disturbance Rejection Control (ADRC) algorithm in large time-delay systems, and the shortcomings of the online calculation of the PI-type Generalized Predictive Control (PI-GPC) algorithm. This paper presents a PI-type Active Disturbance Rejection Generalized Predictive Control (PI-ADRGPC) algorithm. Simulation analysis is also carried out for linear systems, nonlinear systems and large time-delay systems. The analysis results show that the proposed algorithm has better dynamic performance and stronger disturbance rejection ability than the traditional ADRC and ADRC-GPC algorithm.
