I. Project Overview
This project is for the sanitary napkin filler laboratory of the Japanese-funded Kawada company. The initial contractor selected equipment from another manufacturer, which lacked precision control technology, resulting in the project's inability to meet the agreed control accuracy of 23±1°C, 50±2%. After the customer switched to our company's equipment, the high-precision requirements of 23±0.2°C, 50±1% were ultimately achieved.
Data collected via the Internet of Things shows that the laboratory accuracy reached the high precision of 23±0.2°C, 50±1%.
Basically meets the usage requirements for biotechnology research and development
II. Application of Genetic Algorithm in Control Strategy
This project primarily involved inserting a genetic algorithm into the traditional PID algorithm, utilizing an internal FPGA chip for high-speed computation, ultimately evolving stable parameters. Captured curve data from the evolution process:
Evolution process of indoor temperature, showing the continuous narrowing of oscillation amplitude.
Evolution process of indoor humidity
Initial large fluctuations
Subsequent trend towards stabilization
Excellent coil data, mostly above 0 degrees, whereas some manufacturers' equipment suffers from severe icing.
