Discrete time robust control of robot manipulators in the task space using adaptive fuzzy estimator
This paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. A novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. Parameters of the fuzzy estimator are adapted to minimize the estimat...
متن کاملChattering free sliding modes in robotic manipulators control
In this paper the sliding mode motion design is considered for the nonlinear plants which are linear with respect to the control input. The dynamics of the robotic manipulators is treated with and without the dynamics of the actuators. When the dynamics of the actuators is included a design of the sliding modes for the systems with discontinuous control is performed. If actuators’ dynamics is n...
متن کاملDiscrete-time repetitive optimal control: Robotic manipulators
This paper proposes a discrete-time repetitive optimal control of electrically driven robotic manipulators using an uncertainty estimator. The proposed control method can be used for performing repetitive motion, which covers many industrial applications of robotic manipulators. This kind of control law is in the class of torque-based control in which the joint torques are generated by permanen...

متن کاملRobust Finite-time Control of Robot Manipulators
This paper considers finite-time position control of robot manipulators. The robot manipulators are modeled by discontinuous differential equations. In this paper, we prove that the Nakamura’s local homogeneous controller based on a control Lyapunov function is valid to the position control of the robot manipulators, and show the effectiveness of the controller by experiments. Moreover, we comp...
