Abstract
The pump-free multi-hydraulic cylinder group needs to have extremely high synchronous accuracy as an actuator. In order to improve the synchronization accuracy of the control system, the system parameters are optimized by the composite synchronous control strategy of the particle swarm optimization algorithm (PSO-CF-LF) with a contractual factor interact with the learning factor and the ITAE error points. This article is based on the traditional multi-hydraulic cylinder synchronous control system control policy proposes that the PSO-CF-LF algorithm optimizes the three parameters of the PID controller, and then use the ITAE error point indicator to repeatedly adjust the parameters of the three dimensions. Finally, Simulation and experiments show that the multi-hydraulic cylinder synchronous top push hour displacement value of the composite synchronous control strategy using the PSO-CF-LF algorithm is significantly reduced, significantly improved synchronous control performance of the top push system, when the pressure vessel cylindrical housing assembly platform multi-hydraulic cylinder performs the load top push.
