Optimal control of ankle joint moment: Toward unsupported standing in paraplegia [PDF]
, 1998 This paper considers part of the problem of how to provide unsupported standing for paraplegics by feedback control. In this work our overall objective is to stabilize the subject by stimulation only of his ankle joints while the other joints are braced,

A Relay Feedback Method for the Tuning of Linear Active Disturbance Rejection Controllers
IEEE Access, 2020 Active disturbance rejection control (ADRC) is a new control method that estimates the total disturbance by an extended state observer and compensates it by a state feedback law, and good disturbance rejection performance is expected compared to ...

Bearing-Based Formation With Disturbance Rejection
IEEE Transactions on Automatic ControlThis paper considers the problem of the bearing-based formation control with disturbance rejection for a group of agents under the leader-follower structure. The disturbances are in the form of a trigonometric polynomial with arbitrary unknown amplitudes, unknown initial phases, and known or unknown frequencies.

Reset Control for Vibration Disturbance Rejection
IFAC-PapersOnLine, 2019 The high tech industry which requires fast stable motion with nanometer precision continues to mainly use PID which is limited by fundamental linear control limitations. Floor vibrations as disturbance significantly affect performance and their rejection is particularly affected by these limitations.
