A synchronization position control method based on dynamic particle swarm optimization algorithm in electro-hydraulic servo system

For solving dynamic position error problem and improving synchronization position control precision in electrohydraulic servo system, a dynamic particle swarm optimization algorithm is established by means of the introducing of moving windows and forgetting factor in searching regional, and an electro-hydraulic servo system synchronization position control method is presented by dynamic particle swarm optimization algorithm. Finally, this method was demonstrated and validated by a sample. It has shown the proposed method can improve the benefit of position control precision in electro-hydraulic servo system synchronization control, and provide a support for adapting to complex and dynamic synchronization control in electro-hydraulic synchronization position servo system (EHSPSS).
