RBF Neural Network Control for Linear Motor-Direct Drive Actuator Based on an Extended State Observer [PDF]
Discrete Dynamics in Nature and Society, 2016 Hydraulic power and other kinds of disturbance in a linear motor-direct drive actuator (LM-DDA) have a great impact on the performance of the system. A mathematical model of the LM-DDA system is established and a double-loop control system is presented ...

Robust Linear Output Regulation Using Extended State Observer [PDF]
Mathematical Problems in Engineering, 2018 This paper presents a disturbance rejection-based solution to the problem of robust output regulation. The mismatch between the underlying plant and its nominal mathematical model is formulated by two disturbance classes. The first class is assumed to be generated by an autonomous linear system while for the second class no specific dynamical structure
