Outline of Final Research Achievements

In many positioning control systems, the end of positioning phase must be determined correctly in order to initiate the start of the next task. However, the determination is not easy because the output may again exceed the error bound after the output goes into the error bound. If a sufficiently long settling time is introduced to ensure that the output does not exceed the error bound, it results in a longer positioning time. To solve the problem we proposed a systematic method to determine the end of positioning phase in minimum time based on a support vector machine. The effectiveness of the proposed method was verified by performing experiments using a Galvano scanner and a hard disk drive.
