摘要:为提高高速滤棒成型机的分切精度,以刀盘电机与布带轮电机同步控制为目标,采用并行控制方式和交叉耦合结构,利用自抗扰控制原理,设计了交叉耦合自抗扰同步控制器来补偿系统中的同步误差。对设计的控制器进行仿真实验,并与主从控制、交叉耦合PI控制进行性能对比。仿真结果表明,交叉耦合自抗扰同步控制方法具有更好的控制精度和抑制干扰的能力,能有效提高滤棒的分切精度。

The proposed control scheme consists of parallel speed controllers and cross-coupled synchronous controller. Applied with active disturbance rejection (ADRC) control theory, the controller output the compensation to each motor speed controller to decrease the error between two motor. In simulink, the performance of the proposed controller was compared with those of master-slave control and cross-coupled PI scheme. The simulation results shows that the proposed method has higher accuracy and better disturbance rejection ability than those of the master-slave control and PI cross-coupled control, so it can improve the accuracy of rod cutting length.
