| Summary: | The working path of welding manipulator is complex，which requires high smoothness of the planning trajectory，and the planning trajectory needs to meet the kinematics constraints of each joint. An adaptive particle swarm optimization （ADPSO） algorithm with disturbance is proposed，which can plan the optimal trajectory of time，ability and jump under joint constraints. The quintic NURBS curve is used to interpolate the joint working path points，so that the joint position，velocity，acceleration and jump curves are continuous and smooth. The ADPSO algorithm is used for multi-objective optimal trajectory planning. Firstly，the idea of particle extrapolation is combined with particle swarm optimization （PSO） algorithm to enhance the ability of particle search，and then disturbance is introduced to the individual extremum and group extremum to accelerate the convergence speed of particles. Simulation analysis is carried out in Matlab environment， compared with other intelligent algorithms，ADPSO algorithm has better optimization effect and faster optimization timeliness. |
