  • Abstract
    The dynamic performance of the robot is always affected by the parameter uncertainties and unknown disturbance. When the joint positions and velocities of the robot can be measured, the unknown disturbance can be attenuated and the exponential stability can be guaranteed by the state feedback under some conditions. If the joint positions can be measured, but the velocities can´t be measured, the dynamic performance of the close-loop system can be recovered by the high-gain observer.
