We propose a robust high order augmented observer (RHOAOB) based control for nonlinear systems. The RHOAOB is designed to estimate full state and a disturbance. The disturbance includes the unmeasurable external disturbance and model uncertainties for nonlinear systems. The performance of the RHOAOB is analyzed in the frequency domain, as well as the state space. For the output feedback control, the...
This paper proposes a novel robust output feedback controller for an electromechanical system in the presence of external disturbance and uncertainties of physical parameters. By exploiting the cascade features of backstepping design, a simple disturbance observer is proposed to suppress the effects of the uncertainties, and a high-gain observer is applied to estimate the unmeasureable states of the...
Aimed at improving robustness and tracking control performance of electro-hydraulic servo system, an output feedback control scheme is proposed. To estimate the external disturbance and internal parameter uncertainties, the disturbance observer using wavelet neural network is applied. Novel update and control laws are proposed to guarantee that the observer error and the tracking error in the closed-loop...
