Abstract:

To solve the problem of warp knitting electronic shogging system optimization caused by the difference of electrical and mechanical characteristics, the variors parts of system were modeled on the basis of overall control principle, which covered servo drive and motor model, signal conditioning and feedback model, mechanical transmission mechanism, and the whole system simlation model was connected according to the input and output relations of transfer function. The model was verified and compared by MatLab/Simulink. The simulation oscillation gradually converges and quickly stabilizes through the system step response, which verifies the accuracy of the model and the stability of the system. In ouder to further study the dynamic and static characteristics of the system, the speed controller parameters were taken as an example, the system step response of different speed proportional gain was analyzed. The results show that increasing the speed proportional gain is beneficial to the system dynamic response of the electronicshogging system, while the gain increases to a certain value, the system will oscillate and even can't be used.
