In the past, we proposed a time series segmentation approach by combining the clustering technique, the Discrete Wavelet Transformation (DWT) and the genetic algorithm to automatically find segments and patterns from a time series. In this paper, we propose a PIP-based evolutionary approach, which uses Perceptually Important Points (PIP) instead of DWT, to effectively adjust the length of subsequences...
In this paper, we try to automatically induce the membership functions appropriate for the TS fuzzy model. A GA-based learning algorithm is thus proposed to achieve the purpose. The proposed approach considers the shapes of membership functions in fitness evaluation in addition to the accuracy. The shapes of membership functions are evaluated by the overlap and coverage factors, which are used to...
Discontinuous primary permanent magnet linear synchronous motor (DPPMLSM) has many merits in long-stroke transportation, including vertical, horizontal, and slanted model system, however, detent force of DPMLSM is particularly troublesome requiring positioning accuracy specially at low speed region as well as of position control and is different from short primary type and short secondary type PMLSM...
