...Hanad Rasool; Xiaolu Zhu; Muhammad Nabeel Siddiqui; Bilal Afzal Purpose The purpose of this paper is to design an output feedback control algorithm based on a reduced-order observer and a nonlinear disturbance observer ( DO ) for the estimation and rejection of unknown bounded disturbances...

... are replaced with its estimates obtained using the state-observer. Findings The finding includes output-feedback control (OFC) algorithm designed by using a LPO. A modified backstepping model for rotational and rotational systems is developed prior to the design of integral sliding mode control based...

... is equipped with several large flat plates, which can rotate to produce aerodynamic force. Lorentz force can be achieved by modulating spacecraft’s electrostatic charge. An adaptive output feedback controller is designed based on a sliding mode observer to account for unknown uncertainties and the absence...
