Abstract: Focused on the S-shape deviation problem in the narrow fabric production process,this paper introduces an intelligent control system with DC servomotor as the actuator for an intermediate guide roll system.To improve the dynamic performance of the deviation control system and solve the motor vibration problem,the deviation control algorithm is proposed,which is related to intelligent PD feedback control combined with the feed-forward regulation for the system deviation,and its MatLab simulation result shows its good performance and advantages.Furthermore,a technical approach for the deviation controller using high-speed mixed signal micro-controller C8051F020 is presented.The system is applied in the intermediate guide roll system,and the application result indicates that this system is characterized by fast response and steady operation and it is a good solution for the motor vibration.
