Robust Impedance Control
نویسندگان
چکیده
Industrial robots are confronted with performing tasks where a contact with their environment occurs. Therefore, a need for control algorithms with position tracking performance and the force control ability appears. Up to date a lot of algorithms were proposed which deal with robot motion and force control. In this paper a robust impedance control law based on an attractive theory of sliding mode is proposed. The control law guarantees a robot predefined impedance and therefore a force regulation based on the possessed impedance properties is feasible. The proposed impedance controller is used in a force-tracking task. Experimental results on a simple 1DOF mechanism and 3DOF direct drive robot mechanism are reported.

Impedance Control of Robots Using Voltage Control Strategy Revisited
In this note, we show that the impedance control strategy proposed in the paper is not feasible from practical implementation point of view. Next, a robust impedance controller is proposed for electrically driven robots using Fourier series (FS). The fact that robots' actuators have limited voltage is also considered in controller design procedure. In comparison with other impedance controllers...

In this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. The majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. This requires the controller to overcome complex problems such as uncertainties and nonlinearit...

In this paper, a new impedance function is proposed to achieve accurate force tracking under the presence of uncertainties in robot dynamics and environment models. The new impedance function is formulated on the basis of PID control of the force tracking error which compensates for the unknown environment stiiness and position. The robot dynamics uncertainties are compensated by a simple time-...
متن کاملSimulation of Sliding Mode Impedance Control for a 6 DOF Anthropomorphic Robot
Robust control is a way of dealing with model uncertainties that can render the controller less sensitive to modelling errors and disturbances. Herein, the properties of sliding mode control are applied to impedance control to form a robust impedance controller. The proposed controller consists of two parts: a nominal part based on a nominal model of the robot and a robustness part compensating...
