A Model-based Sliding Mode Controller for Robot Manipulators
نویسندگان
چکیده
A generalized model-based sliding mode controller for robot trajectory tracking is proposed, which incorporates the full-order, nonlinear, uncertain actuator dynamics in control law design. The problem of chattering is alleviated by replacing the discontinuous sliding mode control in the vicinity of the sliding mode by a high gain, continuous controller, resulting in dual mode control. Independent joint control, offline feedforward control and online feedforward control laws are derived. Simulation results are presented for the first three links of the PUMA 560 arm to illustrate their effectiveness .

Eliminating chattering phenomenon in sliding mode control of robot manipulators in the joint space using fuzzy logic
In industrial robotic manipulator, due to the presence of quite nonlinear dynamic and structural and nonstructural uncertainties, a precise model is not easily obtained. As a result, designing a controller with a suitable function based on system model is a challenging issue. Sliding mode control is a robust control with numerous applications which can overcome the aforementioned uncertainties....
متن کاملA Novel Robust Adaptive Trajectory Tracking in Robot Manipulators
In this paper, a novel adaptive sliding mode control for rigid robot manipulators is proposed. In the proposed system, since there may exist explicit unknown parameters and perturbations, a Lyapunov based approach is presented to increase system robustness, even in presence of arbitrarily large (but not infinite) discontinuous perturbations. To control and track the robot, a continuous controll...

Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...
