As a new type of magnetic permeability material, amorphous ribbon material has higher magnetic permeability and cost-effectiveness compared with traditional materials, and is widely used in the field of transformer magnetic core manufacturing. The amorphous aluminum alloy with iron as the key element has the characteristics of high saturation magnetic induction and low loss. Due to this characteristic, amorphous alloy materials have a wide application space in the fields of electronics, aviation, aerospace, machinery, and optics. At this stage, with the development trend of electronic information technology towards high frequency and practical application, amorphous ultra-nano-microcrystalline soft magnetic alloy products have already become various magnetic components, replacing silicon steel, metallographic structure and Pumo Alloys are used in the electric power industry, electronic device industrial production and power electronics technology, as transformers, tubular reactors, filters, transformers, control transformers for voltage transformers, power supply transformers, inverter power supplies and program control power transformers device etc. At present, the production scale of amorphous hot-rolled strip is very large, but except for some companies, most manufacturers have chosen offline winding, which will inevitably reduce the productivity of amorphous hot-rolled strip. Therefore, people will conduct research and analysis on the free online unwinding of amorphous tape, and draw conclusions. First of all, we need to design the overall design of the amorphous hot-rolled strip steel coil winding, use the rare earth permanent magnet synchronous motor as the working motor, and master the vector control method of the rare earth permanent magnet synchronous motor. The physical specifications of each roller are calculated and determined, and the type of motor can be used according to the requirements of load inertia matching and output power matching. The main parameter page uses the MFC control module to design in Visualc.0. , carried out the hardware design of the control circuit board based on DSP28335, including Z small system control module, communication control module and human-computer interaction technology control module. The software is developed under the environment of CCS3.3 compiling, including communication program, LCD driver installation and motor control program. The double closed-loop control adjustment of the speed control loop and the current control loop of the rare earth permanent magnet synchronous motor is carried out. Use MFC to write the industrial touch screen of the microcomputer to monitor the operation of the motor online. Finally, the general composition and classification of the supporting force system software are introduced in detail, and the closed-loop tension control method of the constant supporting force winding is obtained. The mathematical analysis model of the supporting force system software using the rare earth permanent magnet synchronous motor as the driving force component is created. The control board of the supporting force loop and the velocity loop is selected according to the state equation Responsive Robust Control (ARC) computer algorithm, and the simulation results show that the design scheme is very reasonable. The design scheme of the support force observer in the departure situation is carried out, and the simulation results conclude the effectiveness of the design scheme. In the Matlab/Simulink control module, the free online winding system software is comprehensively manipulated, the speed curves of each motor are obtained, and the operation of each motor is analyzed, which is consistent with the simulation results.
