Design and analysis of filter of rapier loom′s warp tension control

Design concept and principles of the filter are brought out based on the analysis of noise source and characteristics during controlling rapier loom′s tension.In view of the fact that low pass filter brings lag phase and increases time constant of generalized object,the difficult control degree is defined.The influence of the low pass filter with introduction of different time constants on the design of the controller is analyzed,and the designing method of the warp yarn tension controller is set forth.Matlab′s simulink is used to conduct simulation to verify the effectiveness of the analysis and design of the filter.This study can be used as a basis for designing the actual rapier loom′s tension controller and filter.
