Embodiment Construction
[0058] A temperature control system in transition package based on fuzzy PID of predictive variable domain, including thermocouple (platinum rhodium 30-platinum rhodium 6), PLC controller (SIEMENS-S7-200CN) and heating actuator, the thermocouple is set in transition The package is used to collect the real-time temperature in the transition package, and the collected temperature is fed back to the PLC controller, and the data transmission between the PLC controller and the WinCC host computer realizes data display and storage, and the WinCC host computer and Matlab realize data transmission. The heating actuator includes a power regulator (PAD26-SERIES) and a silicon carbide rod (Φ20*820R500). The PLC controller converts the temperature prediction model in the transition package and the simulation calculation results of the predictive domain controller into a 4~20mA current Drive the power regulator to change the output power of the power regulator, and the power regulator contr...

The invention relates to the field of ultrathin amorphous alloy production, in particular to a system and a method for controlling temperature in a transition ladle based on predictive variable universe fuzzy PID (Proportion Integration Differentiation). Comprising a thermocouple, a PLC and a heating execution mechanism, the thermocouple is arranged in a transition package and used for collecting the real-time temperature in the transition package, collected temperature signals are fed back to the PLC, data transmission is achieved between the PLC and a WinCC upper computer, data display and storage are achieved, data transmission is achieved between the WinCC upper computer and Matlab, and the heating execution mechanism is used for heating the transition package. The heating execution mechanism comprises a power regulator and a silicon carbide rod, the PLC converts the result of the temperature prediction model in the transition ladle and the simulation calculation result of the predictive variable universe controller into current to drive the power regulator, the output power of the power regulator is changed, the power regulator controls the silicon carbide rod to heat, and temperature regulation in the transition ladle is achieved. According to the invention, the problems of poor control effect, instability and the like caused by the fact that parameters cannot be self-tuned in PID control are solved, so that the controller can meet the control process of different states.
Description
technical field [0001] The invention relates to the field of ultra-thin amorphous alloy production, in particular to a temperature control system and method in a transition chamber based on predictive variable domain fuzzy PID. Background technique [0002] Ultrathin amorphous alloys are functional materials with new microstructures. Its preparation technology is completely different from the traditional method. Instead, it adopts the ultra-rapid solidification technology with a cooling rate of about one million degrees per second. From the molten steel to the thin strip, it is formed at one time. Due to the ultra-rapid solidification, the atoms of the alloy solidification are too late Arranged in an orderly manner, the obtained solid alloy has a long-range disordered structure, which is different from the periodic and symmetrical atomic arrangement of metal materials in general, and there are no grains and grain boundaries of crystalline alloys. Due to the characteristics ...
