... effective compensation to the effect of external disturbance as well. First, a novel semiglobal finite-time convergent observer is proposed to estimate the angular velocity in a finite-time under external disturbance. Then, a simple global output feedback controller is proposed by adoption of the designed...

...Junyong Zhai; Chunjian Qian; Hui Ye This paper considers the problem of semiglobal stabilization by output feedback for a class of generalized multi-input and multi-output uncertain nonlinear systems. Due to the presence of mismatched uncertainties and the lack of triangularity condition...

... link angular position, link angular velocity, motor angular position, and motor angular velocity. For output-feedback control, we are able to control the trajectory of the robot manipulator effectively using only link angular position. We consider a trajectory-tracking task of a two-link flexible...

...M. C. Pai; A. Sinha This paper presents a new approach for the robust control of vibration in a flexible structure in the presence of uncertain parameters and residual modes. The technique is based on the sliding mode control algorithm using direct output feedback and assumes that actuators...

...Bin Yao; Li Xu In this paper, a discontinuous projection based output feedback adaptive robust control (ARC) scheme is constructed for a class of linear systems subjected to both parametric uncertainties and disturbances that might be output dependent. An observer is first designed to provide...
