摘　　要：以无轴传动在印刷中应用为背景,系统对卷绕过程中张力变化的一般规律进行研究,并建立数学模型。为了实现恒张力控制,系统引入PFC算法,分别用PFC控制算法和PID控制算法实现无轴传动中恒张力控制系统的仿真。仿真结果表明,在无轴传动这样的多变量、参数时变、速度-张力强耦合系统中,PFC控制算法的控制效果明显优于PID控制算法的控制效果。该仿真系统为搭建实际控制系统提供了理论依据。Take the application of shaftless-driver in printing as the background, this paper discusses the variation principle of tension, and establishes the mathematical model of variable tension value on tension control system. To achieving the constent tension control, the paper introduces PFC algorithm. Both models based on the algorithms of PFC and PID control on shaftless-driver are modeled and simulated. The simulation results indicate that the algorithms of PFC is better than PID control in the complex system with multiple variables, time-varying and strong-coupling characteristics. The simulation system provides a theoretical basis to build the actual control system.
