Shaftless driven technology is a integrated technology, which spans domains within mechanical engineering, control theory,communication theory and transmission technology. Shaftless driven technology can replace mechanism transmission to realize exact transmission. So shaftless driven technology plays an important role and has capacious application foreground in printing, mechanical processing and other fields that needs. This paper takes the shaftless driving technology in printing machine as application background,studying the shaftless drive technology comprehensive,indepth,design the system scheme according to the structure characteristics and system application of shaftless driven technology,completing the design of hardware circuit of shaftless driven on this basis,achieving the synchronization control of multiple motors with Fuzzy-PID control algorithms. The essence of shaftless driven control is multi-motor synchronous control,in order to achieve the synchronization control of multiple motors,adjusting and preticting the motors’speeds timely,the system full applying the proportional relationship of speeds difference of motors and tension,by using intelligent control algorithm-PFC algorithm to simulating the tension control system,achieving constant tension control.In this constant tension control,paper first discusses the variation principle of tension, then 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 driven are modeled and simulated.At the same time,the paper elaborates the proposing、appling、developing、operating principles of PFC algorithm;derivates the application of PFC algorithm in shaftless-driven in pringting machine. The simulation results indicates that the algorithms control of PFC is better than PID in anti-interferencing,stabling and tracking 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.
