An Improved Equivalent-Input-Disturbance Approach for Repetitive Control System With State Delay and Disturbance
TL;DR: An improved equivalent-input-disturbance (EID) approach is devised to enhance the disturbance-rejection performance for a strictly proper plant with a state delay in a modified repetitive-control system and reduces the conservativeness of design by removing the constraints imposed by the commutative condition.
Journal ArticleDOI
Robust Tracking and Disturbance Rejection for Linear Uncertain System With Unknown State Delay and Disturbance
TL;DR: A robust tracking control method is presented in this paper for an uncertain plant with an unknown state delay and an exogenous disturbance that compares with a conventional EID-based method for an unmatched disturbance.
