Parallel robotic structures and their control in SIMULINK environment
Belda, Květoslav
Machine centers for industrial purposes should be accurate and proportionally flexible. One possible direction solving such requirements is utilization of parallel robots. In the paper, modeling and control of such robots are discussed. They are demonstrated by comparative SIMULINK simulation of PID/PSD controllers and discrete model-based predictive controllers. Predictive controllers design control with either mechanical or global model. The global model, in comparison with mechanical, includes drives.
Use of image-processing toolbox for powder particle diagnostics in plasma spray process
Chumak, Oleksiy ; Kopecký, Vladimír
For measurement of distribution of powder particles and their velocities on plasma spraying, imagigng by CCD camera is used.It is difficult to identify the particles injected into plasma jet on photos, because of high brightness of background light source, noises of CCD camera and low contrast of particle images.Filtering of the photos by a function of two-dimensional convolution.
