目前,炼钢厂的多机传动调速系统的同步调速控制方法主要有非耦合控制方式和耦合控制方式,这两种控制方式均以多机传动调速系统中的主电动机为核心控制对象,以主电动机的控制作为控制主轴,在一定程度上忽略了从电动机受到外部干扰和突变对主电动机的影响,造成了传动调速系统的失同步,针对这一问题,在传统控制方法的基础上,在控制逻辑中加入反馈补偿环节,构成一个动态控制主轴,提高了多机传动调速系统调速控制的准确性和抑制干扰能力。
At present, the synchronous control of multi-machine transmission speed control system in steel mills mainly includes the non-coupling control method and the coupling control method. Both of these control methods take the main motor in the multi-machine transmission speed control system as the core control object , To the main motor control as the control spindle, to some extent ignored the motor from external disturbances and mutations on the main motor, resulting in the transmission speed control system synchronization, in response to this problem, the basis of the traditional control methods On the control logic to join the feedback link to form a dynamic control of the spindle to improve the multi-speed transmission speed control system accuracy and suppression of interference.
