Through the in-depth study of working principle and application of PFC algorithm, the paper introduces PFC algorithm to the constant tension control of the system of shaftless driven in printer. In order to better implement constant tension control of shaftless driven control system, the paper choose a first order system as the transfer function of the system of tension model. The paper carries on the silulation of the system’s output of constant tension ,aiming at the situation of the changing of the internal parameters of prediction model for PFC algorithm, such as the attenuation coefficient of reference trajectory , the change of fitting points , prediction horizon and so on, matching of prediction model and tension model of PFC algorithm. The simulation system provides a theoretical basis to build the actual tension control system.
