Synchronous Jacking Control Method of Multi-Electric Cylinder based on Multivariate Synchronization Error Coupling

In order to solve the problems of poor accuracy and system jitter in the application of the traditional deviation coupling step-by-step control structure to the synchronous jacking system of multiple electric cylinders, this paper proposes a synchronous control method of eight electric cylinders based on multivariate synchronous error coupling. By analyzing the limitations of the deviation coupling structure in the synchronous control of eight electric cylinders, a mathematical model for the evaluation of synchronous speed error was established, and a coupling control structure based on multiple synchronous errors was proposed combined with the global synchronous error, which simplified the synchronous controller and realized the high-precision synchronous jacking of the eight electric cylinders. Simulation results show that the control method proposed in this paper can improve the synchronous control accuracy of the whole process of the system and reduce the vibration phenomenon of the system.
