After performing blocks on the whole speech signal, and applying Fast Fourier Transform (FFT) on each blocked signal, the new colored instantaneous mixing signals in frequency domain are constructed. Making use of the Second Order Statistics (SOS), the unmixed matrices are respectively computed at each frequency bin by blind separation based on cost function which is aimed at colored signals. Thus, in time domain, deconvolution is performed after employing correlation-based permutation to the inferred signals which are associated with the unmixed matrices at different frequency bins. The experiment proves the effectiveness of the approach to blind deconvolution by blind separation in frequency domain.","PeriodicalId":375056,"journal":{"name":"2004 International Conference on Intelligent Mechatronics and Automation, 2004.

Through designing the simulatien models of attitude determination for micro satellite, consisted of< the `SGP4 orbit model, the IGRF model and the satellite dynamic model, we do the simulation research. Simulation results with EKF show that, in 1/3 orbit time, the measurement error of attitude angular is controlled within 0.5 deg, meeting the requirement of the micro satellite attitude determination. In addition, we compare the UKF results with the EKF and find the UKF results converge faster than the EKF while the state estimate precision of the two filters are comparable.","PeriodicalId":375056,"journal":{"name":"2004 International Conference on Intelligent Mechatronics and Automation, 2004.

The motion equation can cover a wide class of practical movements in the space. The estimations of the position and motion parameters which are all time-varying are simultaneously developed in the proposed algorithm. The formulated problem can be converted into the observation of a dynamical system with nonlinearities. The proposed observer is based on the second method of Lyapunov. First, the parameters relating to the rotation of the motion are identified, where only one camera is needed. Then the position of the moving object is identified, where the stereo vision is necessary. In the third step, the parameters relating to the straight movement are identified. The assumptions about the perspective system are reasonable, and the convergence conditions are intuitive and have apparently physical interpretations. The proposed method requires minor (I priori knowledge about the system and can cope with a much more general class of perspective systems. Furthermore, the algorithm is modified to deal with the occlusion phenomenon.","PeriodicalId":375056,"journal":{"name":"2004 International Conference on Intelligent Mechatronics and Automation, 2004.

High efficiency machining of turbine blades requires the two sides of the blade to be milled together from top to bottom continuously. Currently available CAD/CAM systems in market have the functions to provide flow line tool paths, but are unable to process complicated surfaces, for example, to mill the whole blade which are trimmed surfaces iin once. This paper introduces the implementation of a new tool path generation algorithm - boundary conformed tool path generation in milling of blade surfaces. With this method, The lirst segment of tool paths is along the top edge of the blade while the end one follows the intersection curve between the blade and the hub surface, those in,between cover the surface by \"morplhing\" smoothly from the start tool path to the end one, the two siides of the blade are machined together from top to bottom with boundary conformed flow line tool paths. This method has been successfully integrated into a commercial CAD/CAM system, ProlEngineer.
