In this paper, an evolutionary algorithm is used for developing a decision support tool to undertake multi-objective job-shop scheduling problems. A modified micro genetic algorithm (MmGA) is adopted to provide optimal solutions according to the Pareto optimality principle in solving multi-objective optimisation problems. MmGA operates with a very small population size to explore a wide search space...
Optical flow estimation is one of the key technologies in computer vision and image processing. However, constancy of the grey value which is used in traditional variational optical flow computation technology is sensitive to the constant changes of illumination and non-translational displacements. To solve this problem, the advanced data terms including the gradient value constancy assumptions and...
This paper presents a new Class-E power amplifier (PA) with a -matching output network. The PA is targeted at low output power wireless applications. Analytical formulae are derived to aid the PA design, characterization and optimization. A fully integrated 2.4-GHz PA for short distance communications has been implemented in 0.13 CMOS technology to verify the proposed design method...
For the three-phase pulse-width modulated (PWM) rectifiers, the controller's performance can be influenced by the mathematic model error, parameter variation and external disturbances, etc. This paper presents a robust H∞ control method for the PWM rectifiers to improve the control performance. The outer voltage loop controller and the inner current loop controller are designed separately. Based on...
This paper studies on the design of planar bus bar in the high-power converter. Firstly, the impedance characteristic of planar bus bar and the performance of EMI are analyzed. The design of planar bus bar is restricted by the spatial layout for physical devices. The traditional design method, the partial element equivalent circuit (PEEC), is based on the assumption that the current was uniformly...
