Abstract：In industrial production,due to long-term use,In industrial production,due to long-term use,inconsistent system parameters on both sides of the crystallizer may occur and other uncertain factors,which lead to synchronous output errors between the two subsystems of the crystallizer and affect the quality of the cast billet.To reduce the synchronous output error of the two subsystems of the mold,improve the quality of the casting billet and reduce the labor cost.this article proposes an adaptive PID synchronous control strategy for continuous casting mold driven by hydraulic servo with PID control.The mathematical model of continuous casting crystallizer driven by hydraulic servo system was derived,and the continuous casting mold was modeled through a simulation system to simulate the actual industrial production crystallizer.Particle Swarm Optimization(PSO)and Genetic Algorithm(GA)were used to call the constructed model and optimize its PID parameters.Through simulation verification,the PID parameters optimized by intelligent algorithms have a small synchronization errors,achieving the effect of adaptive synchronization control and meeting the indicators of industrial production.
