Abstract


With the development and application of science and technology , the basic strip unwinding , rewinding , send workflow automation , but due to the impact of uncontrollable factors likely to bias strip retractable automated process , the quality of the product by seriously affected. To this end , the subject on the basis of the basic principles of research corrective control system , the analysis of the infrared detection photoelectric sensor , control motor performance , focuses on corrective control algorithm in the control system , the establishment of the correction system 's mathematical model and simulation using MATLAB simulation and in the experimental stage to verify the effectiveness of the control algorithm for rectification . This article describes the status of corrective control system , compared to the controller difference at home and abroad , the proposed control strategy to speed up the the correction system response time and reduce the shock of the control system , analyzed the reasons for the deviation in the working process of the strip and to reduce the control deviation the commonly used measures . This system is the infrared sensors to detect the offset amount of the strip , and then is A / D converted into a digital controller can identify , and the linearity of the sensor detects the offset and the digital voltage will affect the corrective quality . This topic focuses on the \Analysis of the influence of each parameter in the system under the control of the system simulation curve , with the purpose to adjust the parameters to improve the quality of control . Proposed offset the \combination , the ultimate controller optimal output or close to the optimal output . Software system using C language programming , and verified by experiments in ICE3TEK-F2812-A test bench of intelligent PID algorithm , improve the effectiveness of the system corrective ability to verify the theory , the actual reference value to improve the level of domestic corrective .
