Parallel robot possesses the characteristics of large rigidity, strong load bearing capacity and small error. Directed against the parallel robot mechanism with AC servo-motor driveparallel mechanism, a model of controlling system was established, and a track planning in its working space has been carried out. After that a kind of dynamic sliding mode control algorithm was designed, and a simulative experiment was made on the Matlab/Simulink. The result shows that this algorithm is good in the system, and achieved high precision real-time control on this parallel robot.

Background: A novel type of control strategy is presented for control of chaotic systems particularly a chaotic robot in joint and workspace which is the result of applying fractional calculus to dynamic sliding mode control. Objectives: To guarantee the sliding mode condition, control law is introduced based on the Lyapunov stability theory. Methods: A control scheme is proposed for reducing the chattering problem in finite time tracking and robust in presence of system matched disturbances. Conclusion: Also, all of chaotic robot's qualitative and quantitative characteristics have been investigated. Numerical simulations indicate viability of our control method. Results: Qualitative and quantitative characteristics of the chaotic robot are all proven to be viable thru simulations.

For a class of linear MIMO uncertain systems, a dynamic sliding mode control algorithm that avoids the chattering problem is proposed in this paper. Without using any differentiator, we develop a modified asymptotically stable second-order sliding mode control law in which the proposed controller can guarantee the finite time convergence to the sliding mode and can show that the system states asymptotically approach to zero. Finally, a numerical example is explained for demonstrating the applicability of the proposed scheme.
