Data-Driven Learning Extended State Observers for Nonlinear Systems:Design,Analysis and Hardware-in-Loop Simulations

摘要

Dear Editor,This paper considers the disturbance/uncertainty estimation of first-order nonlinear system subject to fully unknown internal dynamic,external disturbance,and unknown control input gain.Compared with existing extended state observer(ESO)where priori knowledge of model parameter such as nominal input gain should be known as a priori。
