AbstractTitle： Abstract Title： RESEARCH ON FlBER PULLING MACHlNE’S CONTROL SYSTEM Major：Measurement．Metrology and Instrumentation Name：Kun wANG Signature：土逝 Abstract 群 Supervisor：Associate Prof．Dianhong YU Signature： Associate Prof．Ming JIANG Signature： Fiber pulling machine plays all important role in fiber produce．The control result of pulling servo motor is an important point which affects the quality of fiber．Fuzzy control system based on MCU has been designed to get satisfying control results．The question of time delay in control system has been analyzed in theory．And fuzzy control algorithm based on the Smith predicator has been designed to resolve the problem of time delay．Four contents are mainly included as follows： First，on the basis of the analysis of fiber pulling machine’s working principle，the fiber pulling machine servo system and the fiber diameter measurement part have been designed and developed．At the same time，the type of pulling servo machine has been selected and the control algorithm has been decided． Second，according to the workers’experience and fuzzy control theory,the-fuzzy control algorithm of fiber pulling machine has been designed and also has been applied in the fiber pulling machine control system．In order to realize the algorithm，the calculation process has been divided into two parts which include on—line part and off-line part．On the off-line part， fuzzy query table has been calculated by using MATLAB．On the on—line part，the fuzzy control has been realized by looking up the fuzzy query table． Third，fuzzy control system based on MCU has been designed in order to realize the close loop control of fiber pulling machine．Fiber diameter real—time acquisition and data processing have been made experimentally．The hardware and software of the fuzzy control system have been designed and put into use successfully．By using the fuzzy control system，the automation of fiber manufacture has been realized and the satisfying contro
