A novel transmission and control system for twisting machine based on PCI bus

Most of the control systems of the latest twisting-machine adopt the multi-motor drive system.However,at present in China,the use of single chip processor for its control is still popular.Aiming at the shortcomings of the control system,a new type transmission and control system based on PCI bus technology is developed,which is a multi-motor transmission system of four motors.An appropriate mathematic model has been developed.The running of spindles,the winding of bobbins and the reciprocate of guiding-yarns are controlled in phase by the control system,which is based on the integration of the AC servo technology,the frequency conversion technology,the PCI local bus technology and the twisting theory.Experiments show that the design of the transmission and control system can achieve the process objectives of winding of the latest twisting machine.
