Application of Adaptive Disturbance Observer Control to an Underwater Manipulator
Hydrodynamics of the manipulator mounted on the vehicle are poorly known and time-varying. Furthermore, its motion is disturbed by the vehicle motion and current. This paper presents a non-regressor based adaptive control scheme with a disturbance observer for tracking the trajectory of underwater mobile platform-mounted manipulators. The presented control system does not require any informatio...
متن کاملA Sliding Mode Control based on Nonlinear Disturbance Observer for the Mobile Manipulator
A sliding mode control based on nonlinear disturbance observer is presented in this paper considering the tracking control of mobile manipulators. The proposed control strategy adopts the nonlinear observer to estimate the bounded external disturbances and overcome the effects. In addition, the stability of the controller is verified by Lyapunov theory. Finally, the simulation results verify th...
متن کاملRobust H_∞ Controller design based on Generalized Dynamic Observer for Uncertain Singular system with Disturbance
This paper presents a robust ∞_H controller design, based on a generalized dynamic observer for uncertain singular systems in the presence of disturbance. The controller guarantees that the closed loop system be admissible. The main advantage of this method is that the uncertainty can be found in the system, the input and the output matrices. Also the generalized dynamic observer is used to est...
متن کاملVoltage Control and Load Sharing in a DC Islanded Microgrid Based on Disturbance Observer
Increasing DC loads along with DC nature of distributed energy resources (DERs) raises interest to DC microgrids. Conventional droop/non-droop power-sharing in microgrids suffers from load dependent voltage deviation, slow transient response, and requires the parameters of the loads, system and DERs connection status. In this paper, a new nonlinear decentralized back-stepping control strategy f...
متن کاملSliding Mode Control of the Master Manipulator Based on Disturbance Observer
Abstract A sliding mode control (SMC) with improved exponent reaching law based on disturbance observer (DOB) is proposed for the robot control, to solve the problem of robot system which is vulnerability to external interferences and has some uncertainties. The disturbance observer (DOB) would detect and compensate external disturbances and uncertainties in the robot system, so that the moveme...
