Abstract :
Anti-interference motion control and elastic vibration synchronous suppression of base and joints for an elastic-base elastic-joint space robot with uncertainties are studied. On the basis of equivalent linear spring assumptions about the elastic base and joints, the dynamic equations of the space robot are established, then both singular perturbation slow and fast subsystems are deduced with the equivalent stiffness concept. The traditional parameter adaptive control law is improved by using σ modification, and is then combined with the robust anti-interference control. An improved singular perturbation adaptive robust anti-interference control scheme is proposed for the slow subsystem to track the rigid motion trajectories of the base's attitude and links' joints subject to uncertain parameters and bounded external disturbances. A high-gain linear state observer is employed to measure the fast higher-order states in real time, and an improved optimal control method is designed for the fast subsystem to synchronously suppress the elastic vibrations of the base and joints. Simulation result demonstrates the validity of the presented hybrid control scheme in anti-interference motion control and vibration suppression of the space robot.

Abstract :
The sliding-mode neural network control problem was discussed for a flexible-joint dual-arm space robot under the influences of parametric uncertainty and external disturbance. The elastic deformation of joint was described by the linear torsion spring, in terms of the principle of linear and angular momentum and the Lagrange method, the dynamic model of flexible-joint dual-arm space robot was derived. By using of the singular perturbation approach, two subsystems which can be controlled independently were separated from the system with the joint flexible compensation. To realize the accurately trajectory tracking of end-effectors on the effects of two uncertain factors and suppress the elastic vibration of joints, a hybrid control scheme composed by the sliding-mode neural network control of rigid motion and the feedback control of flexible motion was put forward. Simulation results show that the presented scheme has stronger ability to resist disturbance and parametric uncertainty, and can control the system to perform the desired circular motions and suppress the elastic vibration of joints. ©, 2014, Chinese Association for System Simulation.

Abstract :
The coordinated control and vibration suppression problems of free-floating flexible space manipulator system with external disturbances and uncertain or unknown parameters are discussed. The flexible links are approximated based on the assumed mode method, and then with the second Lagrange approach and the linear momentum conservation, the dynamic equations of free-floating flexible space manipulator system are derived. Nonlinear robust control and nonlinear robust adaptive control schemes are proposed for coordinated motion of the free-floating flexible space manipulator system. These control schemes can all overcome the effect of external disturbances on the free-floating flexible space manipulator system and control the base attitude and the joints to complete the desired coordinated motion, while suppressing flexible vibration of the links efficiently. In addition, the nonlinear robust adaptive control scheme can also solve the uncertain or unknown problem of system inertial parameters. Numerical simulation is carried out to verify the validity and feasibility of the proposed control schemes. © 2013 Journal of Mechanical Engineering.
