Research on multi-cylinder coordinated coupling synchronous control strategy based on strain energy

Multi-cylinder synchronous control is critical for heavy machinery lifting operations, yet struggles to maintain precision under dynamic and asymmetric loads. Traditional strategies neglect the dynamic coupling between structural strain energy and hydraulic actuation, leading to energy accumulation and synchronization errors. This paper proposes a coordinated coupling control strategy based on dynamic strain energy balance. By decoupling lifting processes from synchronization control and integrating real-time strain energy feedback, the method dynamically compensates for deformation-induced deviations. A multi-physics co-simulation platform (MATLAB/AMESim-Adams) validates the approach, demonstrating significant improvements in synchronization accuracy and stability over conventional methods. Experimental results show the strategy reduces maximum synchronization errors by nearly half under variable loads while suppressing structural fatigue risks. This work advances high-precision multi-cylinder system design, with broader applications in heavy equipment requiring robust cooperative control.
