In this document, an underactuated two degrees–of–freedom control moment gyroscope
(CMG) is studied. Specifically, the problem of trajectory tracking in the non-actuated joint is …

This paper presents an experimental platform for regulating the DC motor angular speed
powered by photovoltaic cells. The experimental platform comprises an Eco Green Energy …

This paper proposes an output feedback controller with a linear extended state observer
(LESO) for an n-degree-of-freedom (n-DOF) manipulator under the presence of external …

This paper presents a systematic procedure for the control scheme design for a PVTOL
aircraft system with an inverted pendular load, which is a nonlinear underactuated system …

To reduce the phase lag introduced by extended state observer (ESO), an reduced-order
active disturbance rejection control (RADRC) method is recommended. This paper …

This paper presents a robust control regarding position control of an electro-hydraulic rotary
actuator (EHRA) system under the presence of the lumped uncertainties such as the variant …

This paper considers an active disturbance rejection problem of a singular time-delay
system with unknown external disturbances. By using an equivalent-input-disturbance (EID) …

In this article, the problem of designing Active Disturbance Rejection Control (ADRC) for a
class of second-order mechanical systems, expressed with Euler-Lagrange equations, is …
