摘要：In this study, a temperature control algorithm based on PID control scheme was proposed for roll-to-roll embossing. The roll surface was heated using induction coils and cooled with circulating water, where the temperature of the roll surface was feedback controlled by the control algorithm that we proposed. Proportional band (PB), integral time, and derivative time components of the PID controller were calculated by the relay feedback method and the reaction curve method. The release of the controller output and connection between the roll and chiller were both simply switched on/off based on the margin between desired temperature and current temperature. The temperature controller rapidly raised roll temperature and shortened the cooling time by choosing an appropriate temperature margin. Consequently, the roll-to-roll embossing system equipped with the proposed controller may decrease the time required to find the optimal embossing process parameters
