| Abstract: | Noise processing with classification method is brought out based on analysis on noise source and characteristics in rapier loom’s tension control. Analog low-pass filer design method to high-frequency noise and random noise is analysis based on definition of difficult control degree. Method of Frequency spectrum used to obtain period and coherent mean method used to obtain periodicity noise are designed to compensate periodicity low-frequency noise and improve control system’s performance. Analysis and design method’s effectiveness are verified based on simulation of matlab’s programming and simulink and as a basis of actual rapier loom’s tension control filter and controller design. |
