A common approach for simplification analysis of complex dynamic model is presented, and the simplified dynamic model of a spatial 6-DOF parallel motion system with high computational efficiency is proposed for high real time control. By using Kane method, the full dynamic model of a spatial 6-DOF parallel motion system viewed as 13 rigid bodies is built. With rigid body decomposition, the full dynamic...
This paper addressed the dynamics and control for completely spatial 6-DOF parallel robots (SPR) in computer. The complex dynamic equations are derived via using Kane methods, and a typical PID controller is developed for spatial 6-DOF parallel robots. Making use of the software of Simulink, the computer model of SPR is built in terms of the dynamic equations of SPR, and the simulation is realized...
A novel model-based controller for 6 degree-of-freedom (DOF) hydraulic driven parallel manipulator considering the nonlinear characteristic of hydraulic systems-proportional plus derivative with dynamic gravity compensation controller is presented, in order to improve control performance and eliminate steady state errors. In this paper, 6-DOF parallel manipulator is described as multi-rigid-body systems,...
