Abstract

Feedforward control is widely used in industrial robot as a valid control method. High speed motion will bring the vibration for robot with flexible joints, which will affect the dynamic performance of robot. The residual vibration character is analyzed for palletizing robot using feedforward control method in this paper. Considering the vibration suppression constraints polynomials fitting method is used to compute the discrete data of trajectory. Meanwhile, the discrete trajectory points are fitted based on Fourier series function. The trajectory fitted model is optimized using genetic algorithm, and the high frequency harmonics included in feedforward drive torque is decreased under the premise of guaranteeing fitting precision and boundary continuity. Simulation results verified the rightness of the proposed trajectory planning algorithm.
