According to company sales manager Yu Jianhua, hanging wall of the machine, circle are used electronic needle selection, at the same time with jacquard and loop transfer function, including the hanging wall of the road configuration shift circle triangle, the 4-way configuration ring moved the triangular ring; plus machine automatic thread regulating function and computer controlled speed rolling function, servo needle pressing device and pneumatic para mediation, so as to realize the full electronic control.
This paper presents an analytical method for determining the controller parameters based on the open-loop frequency transfer function of regulating systems.
By introducing a digital dual-loop control model of inverter feedback with the capacitor current, the system transfer function is figured out and its external characteristic is analyzed.
In order to minimize the H∞ norm of the transfer function from the disturbance to the tension, the H∞ controller was designed using the Matlab toolbox, and the PI controller was designed for compare, also the amplitudefrequency characteristic of the disturbance to tension in the closed loop control system was analyzed and the control system was simulated use sinusoidal signal at different frequency and speed.
