## 3 Method: Unbalance Prevention Control in Dehydration Based on BO
### Construction of GAUS (Global Auto UB-Table Tuning System)  
To automatically optimize the unbalance prevention control specifications in the washing machine dehydration process, we developed GAUS, which automates vibration control experiments, manages data, and optimizes control specifications using artificial intelligence. GAUS consists of three main components: the vibration measurement and test automation system, the test information management system, and the UBT tuning automation system, as illustrated in Figure 4.  
The first component, the vibration measurement and test automation system, measures in real-time the vibrations generated during the actual washing machine dehydration process and automatically conducts experiments to verify the effectiveness of the control specifications (UB Table). In traditional practice, an engineer would manually modify the UB Table, compile the updated code, and download it to the washing machine. However, with GAUS, changes to the UB Table can be immediately reflected in the washing

This automated Microm Write program takes the standardized table of UB parameters and transmits them to the washing machine's MCU (Microcontroller Unit) through serial communication. The actual process is designed so that an automatic script runs upon a simple button click in the Microm Write software. Various vibration sensors are installed at multiple points on the tub and cabinet of the washing machine, collecting vibration data from different axes. At the same time, the washing machine's internal device data (time, RPM, UB values, stage information, and internal sensor readings) and external vibration data are automatically logged as test data. Both the machine's internal data and the collected vibration data are transmitted via the vibration measurement system to the test information management system. This data is then utilized by the UB Table Tuning automation system to update the control specifications. Thus, the test automation system reflects the control specification changes made by the UB Table Tuning automation system onto the washing machine's control MCU and carries out tests of the washing machine's dehydration performance. By automating the experimental process--no manual intervention required--the system significantly accelerates the optimization of unbalance prevention control specifications. The second component, the test information management system, provides remote management of actual UB tests in the field, including test planning and UB Table registration, monitoring of test progress, and storage of test results. It also manages databases for ongoing tests, vibration measurement results, and test log data, as well as scheduling and running repeated tests indefinitely. This test information management system manages all test data within the system, systematically collecting any data generated during the testing process. As a central data repository, it oversees data flow between the vibration measurement/test automation system and the UB Table Tuning automation system. It stores the large volume of test data, and based on that data, supplies what the optimization algorithm needs to improve the control specifications. It also forwards improved UB Table proposals generated during testing to other systems, thereby providing integrated data management and system-to-system data linkage. The third component, the machine learning-based UB Table Tuning automation system, serves as the \"brain\" that creates and fine-tunes an optimized UB Table for unbalance prevention control. It uses the data provided by the test information management sys
