FIBER TENSION CONTROL APPLYING ADAPTIVE FUZZY-PID CONTROLLER

Abstract

Tension control is a process that can be found in many industrial process such as paper production, rolling mills, and winding process. This thesis presents fiber tension control for fiber winding process required for Fiber Optic Gyroscope (FOG). The tension control during winding process of fiber optic rings, used for FOG, is vital. Poor tension control could destroy expensive lengthy fiber or produce FOG with poor performance. In this thesis, a proposed mechanism of tension transducer that relaxes the control objective and perform tension control using one control loop is introduced. The mathematical model of winding process with transducer and control mechanism is established. A simulation of the model with different characteristics is introduced. The results are analyzed to verify the control mechanism and the developed model. The results shows that the proposed control mechanism has fast response for rejection of tension disturbance. The thesis is organized in five chapters as follow: Chapter one contains an introduction and identification to the different types of gyroscopes, list their advantages and disadvantages and their application. Moreover, working principle of FOG and its structure is introduced. Chapter two provides an overview on gyroscopes. It gives brief information ab
