In many practical applications, several factors make sampled-data systems operate non-uniformly. In these systems, the sampling and control signal updating time intervals are variable. These systems are generally non-periodic and time-varying. Therefore, controller design is usually difficult. In this paper, we design H2 controller for non-uniform sampled-data systems. Because these systems are time-varying,...
In this paper, we propose a novel approach for colourizing of multichannel MR images based on real colour of human brain. At first, we use independent component analysis (ICA) to transfer three MR modalities into different representations, which enhance the physical characteristics of tissues. Then, Statistical Features are extracted from three independent components and their wavelet coefficients...
This paper first will describe @Home Mobile Robot and DC motors. In continuous, is designed a Direct current (DC) motor for special task due to specific speed diagram for considered robot. This robot wants to work in intermittent operation condition. Finally is done a speed control on a selected permanent magnet brushed DC motor using of Linear-Quadratic-Regulator (LQR), Linear-Quadratic-Gaussian...
