Abstract

The control of position and trajectory tracking are critical issues in parallel robots. Traditional PID tracking algorithms, which are based on kinematics control use the position and speed deviation as a negative feedback in order to design a controller. However, this method is not only hard to maintain the excellent dynamic and static quality of a system, but it is also incapable of realizing complete decoupling, and it needs large energy to be controlled. To overcome such drawbacks, this paper proposes, a computed torque decoupling control strategy for a 3-RSR spheroid parallel mechanism. The control strategy includes a computed torque decoupling control method with traditional PD controller and self-adaption fuzzy controller. It was proved that the corresponding Lyapunov function is global asymptotic stable in the ideal and non-ideal estimation. A set of ADAMS-MATLAB dynamic simulations were established based on virtual prototyping technology. The results demonstrated that the performance of the control scheme with self-adaption fuzzy controller is more effective than that with PD controller.
