Torque control strategy is a common strategy to control robotic manipulators. However, it becomes complex duo to manipulator dynamics. In addition, position control of Permanent Magnet Synchronous Motors (PMSMs) is a complicated control. Therefore, tracking control of robots driven by PMSMs is a challenging problem. This article presents a novel tracking control of electrically driven robots wh...

A Space Free-Flying Robot (SFFR) includes an actuated base equipped with one or more manipulators to perform on-orbit missions. Distinct from fixed-based manipulators, the spacecraft (base) of a SFFR responds to dynamic reaction forces due to manipulator motions. In order to control such a system, it is essential to consider the dynamic coupling between the manipulators and the base. Explicit d...

a mobile manipulator robot is known as a complex system due to some properties such as coupling between the manipulator and mobile chassis, holonomic and nonholonomic constraints, multivariable and nonlinear dynamics. the control of robot faces the external disturbance, parametric uncertainty and unmodeled dynamics. therefore, the use of an adaptive fuzzy system is suggested for its capability ...

There are many occasions where the base of a robotic manipulator is attached to a moving platform, such as on a moving ship, terrain or space shuttle. In this paper a dynamic model of a robotic manipulator mounted on a moving base is derived using both Newton-Euler and Lagrange-Euler methods. The presented models are simulated for a Mitsubishi PA10-6CE robotic manipulator characteristics mounte...

cable driven parallel manipulator (cdpm) is a special class of parallel manipulator in which the rigid extensible links are replaced by actuated cables. it is necessary to take into consideration the cable dynamics, i.e.; its mass, flexibility and curved shape for manipulating a long-span cdpm. these terms complicate governing equation of motion in a way that special tactic are applied for simu...

A free-floating space redundant robotic manipulator dynamics model is established and the dynamics equation is derived, the delayed feedback control time and the self-adaptive gain coefficient are obtained by substituting into delayed feedback control equations. Then simulated dynamics control chaotic motion of the space redundant robotic manipulator, the simulation results show that the chaoti...

In this paper, adaptive control of free-floating space manipulators is considered. The dynamics based on the momentum conservation law for the free-floating space manipulator has non-linear parameterization properties. Therefore, the adaptive control based on a linear parameterization model cannot be used in this dynamics. In this paper, the dynamics of the free-floating space manipulator syste...

Cooperating with heavy forging press, the heavy-duty forging manipulator is used for handling the workpiece during the free-forging process. Therefore, the size accuracy of the forgings is related to the dynamics performance of the forging manipulator. This paper aims to study the dynamic performance of DDS heavy-duty forging manipulator. The kinematics model is firstly built to predict the tra...
