摘　　要：目的为了实现在高强度复合纸板生产过程中对分切机输送速度的精确控制,以提高纸板的整体强度和生产效率,研究电机速度控制的方法。方法介绍高强度复合纸板的制作工艺流程,并围绕分切机中驱动电机的速度控制进行硬件系统设计,采用PID控制和模糊控制的复合嵌套控制方法,设计一套参数自整定的模糊PID速度控制系统,并进行系统仿真。结果模糊PID控制系统的超调量小于5%,调节时间比传统PID控制方法缩短30%以上,调节后期的振荡基本消除。结论模糊PID的复合嵌套控制方法具有超调很小、响应速度快等优越性,改善了系统的动态性能,增强了系统的抗干扰能力。Objective To accurately control the feeding speed of the Cross-Cut machine during the manufacturing process of the high-strength paper board, which will help to improve its integral strength and production efficiency, the method of control- ling the motor speed was studied. Methods Firstly, the manufacturing flow of the high-strength composite paper board was in- troduced, and a hardware system focused on the speed control of the Cross-Cut machine was designed. A nested control meth- od with PID and fuzzy control was adopted for designing the fuzzy-PID speed control system, which was capable of self-tuning its parameters, and the system was simulated. Results The overshoot of the Fuzzy-PID control system was less than 5%, the adjusting time was reduced by more than 30% in comparison with the traditional PID control method, and the oscillation was almost excited at the late stage. Conclusion This nested fuzzy-PID control has the advantage of low overshoot and fast response, which improves the system＇s dynamic property and strengthen its anti-interference.
