In order to deal with the uncertainties and nonlinearities within a permanent magnet line synchronous motor (PMLSM) vertical servo system, such as friction, thrust ripple and external disturbance, an indirect adaptive fuzzy (IAF) controller designed. The IAF controller comprises a supervisory controller and an equivalent controller. The supervisory controller is proved to guarantee the tracking error...
The paper addresses the problem of factorization based structure and motion recovery under perspective projection. Two new algorithms are proposed to improve the performance of perspective factorization. First, we propose to initialize the projective depths via a projective structure reconstructed from two views with large camera movement, then optimize the depths iteratively by minimizing reprojection...
The problem of camera self-calibration and Euclidean reconstruction from image sequences is addressed in the paper. We propose a quasi-perspective projection model and apply the model to structure and motion factorization to estimate the focal lengths of the cameras. Then we optimize the camera parameters based on Kruppa constraints and recover the metric structure from factorization of the normalized...
