2021-10-21

Amorphous ribbon material as a new type of magnetic permeability raw material, compared with traditional raw materials, has higher permeability and cost-effective economic benefits, and is widely used in the manufacturing industry of transformer magnetic cores. Amorphous aluminum alloy with iron as the key element has the characteristics of high saturation magnetic induction and low loss.


Because of this feature, amorphous alloy raw materials have a wide indoor space for use in industries such as electronic devices, airlines, aerospace, mechanical equipment, and electronic optics.


At this stage, with the development trend of electronic information technology towards high frequency and practicality, amorphous, ultra-nano, and microcrystalline soft magnetic alloy products have long become a variety of magnetic components, replacing silicon steel, metallographic structure and general purpose. Alloys are used in the power industry, electronic device industry production and power electronics technology, as voltage transformers, power supply transformers, inverter power supplies and program control power transformers, tube reactors, filters, transformers, control.


At this stage, the scale of production and operation of amorphous hot-rolled steel is very large, but with the exception of some companies, most manufacturers have chosen offline winding, which will inevitably reduce the productivity of amorphous hot-rolled steel. Therefore, people will carry out scientific research and analysis on the free online unwinding of amorphous ribbons, and draw conclusions.


People must design the overall plan for free online winding of amorphous hot-rolled strip steel, use rare earth permanent magnet synchronous motors as the working motors, and master the vector control mode of rare earth permanent magnet synchronous motors. Measured and clarified the physical specifications of each roller. According to the regulations of load inertia pairing and output power pairing, the type of motor can be applied. The main parameter page selects the MFC control module to design the scheme in Visualc.0.


Carried out the hardware design of the control circuit board based on DSP28335, including the minimum system control module, communication control module and human-computer interaction technology control module. Software development is compiled under the natural environment of CCS3.3, including communication program flow, LCD driver installation and motor control program flow. The double closed-loop control adjustment of the rare-earth permanent magnet synchronous motor speed control loop and current flow control loop is carried out. Use MFC to compose the industrial touch screen of the microcomputer to carry out online monitoring of the operation of the motor.


The general composition and classification of supporting force system software are introduced in detail, and the closed-loop control tension control method of constant supporting force winding is obtained. A mathematical analysis model of the supporting force system software with rare earth permanent magnet synchronous motors as the driving force components is created. The control board supporting the force loop and the speed loop is selected by the ARC computer algorithm based on the state equation, and the simulation results conclude that the design scheme is very reasonable.


The design plan of the support force observer for the departure situation is carried out, and the simulation results have concluded the effectiveness of the design plan. In the Matlab/Simulink control module, the free online winding system software was comprehensively manipulated, and the speed curve of each motor was obtained, and the operation of each motor was analyzed, which was consistent with the simulation results.
