摘　　要：造纸机张力控制系统具有动力学模型变化大,张力和速度强耦合,干扰较多的特点,而且生产环节众多,具有许多不可测因素。由于纸机的这些特点,传统的PID控制,已不能满足生产要求,所以提出了内模张力控制方法,对收卷段设计了控制器并进行了仿真,仿真结果表明,内模张力控制系统比传统的PID控制具有更好的性能,实现张力的稳定控制,同时能够克服外界干扰的影响。The tension control system of the papermaking machine has the characteristics of great dynamic change,strong coupling between linear velocity and tension,and many sources of disturbance. According to the characteristics of the tension control system,it is difficult to control tension and the traditional PID control cant meet the requirements of tension. Therefore IMC controller is designed and make the simulation for winding segment, the simulation results show that IMC controller is better than the traditional PID control to achieve stable control of the tension at the same time be able to overcome the impact of external interference.
