摘　　要：为抑制电流波动所导致的轧机主传动系统扭振现象,建立直流电机驱动下的轧机主传动系统动力学模型,分析电流波动对主传动系统扭振的影响规律。在Simulink中分别对PID和LADRC两种控制器作用下的扭振系统进行仿真分析,验证了LADRC控制器的优越性,进而对其整定参数通过粒子群算法(PSO)进行最优求解,发现粒子群算法最优解的控制器具有响应速度快、追踪精度高的优势。研究结果表明LADRC对轧机主传动系统的扭振有很好的抑制效果。In order to suppress the main drive system torsional vibration of rolling mill caused by current fluctuation,a dynamic model of the rolling mill main drive system driven by DC motor was established to analyze the influence of current fluctuation on the torsional vibration of the main drive system.The torsional vibration system under the action of PID controller and LADRC controller was simulated and analyzed respectively in Simulink to verify the advantages of LADRC controller,and then the tuning parameters were optimized by PSO(particle swarm optimization)algorithm,It was found that the controller with the optimal solution of PSO algorithm has the advantages of fast response speed and high tracking accuracy.The results show that LADRC has a good inhibition effect on torsional vibration of the mill main drive system.
