Multi-Resolution modeling techniques have been used in various fields, but the application in radar system simulation is still in the exploratory stage. In this paper, the multiresolution modeling techniques used in radar system simulation, the hierarchical, modular modeling system, Set up corresponding to different requirements of different resolution model library with the multi-resolution modeling...
A mathematical model that describes the rotation speed regulation process of a main engine system is established. Then an adaptive control system is designed for the control of main engine rotation speed. The adaptive control system makes self-organizing through modification of its weighted values which are determined through correlative search, as well as a coefficient of smoothness is adopted to...
Electromagnetic tomography (EMT) sensing system with multi-excitation-modes is introduced. It can produce three excitation modes, among which the quasi-parallel excitation mode can give more independent projections than the parallel mode and produces relatively more even sensitivity distribution than the coil-pair mode. A new kind of image reconstruction algorithm based on inverse problem is proposed...
Electromagnetic Tomography technology has bright future in the two-phase flow measurement, and the study of the image reconstruction algorithm is important to improve the measurement accuracy. A new kind of algorithm based on Modified Newton-Raphson method was proposed and applied to the EMT image reconstruction for solid-gas two-phase flow measurement. The simulated reconstruction results of the...
In this paper, the geometrical similarity scale-up theoretical model of rotor structure in mixer is established according to the rheology theory of rubber mixing process .The mixer is designed by adoption of the model formula, using several geometrical proportional coefficients of which the solving method have been found .The designed mixer is compared with the prototype mixer, the results showed...
Firstly, a mathematical model of main engine cooling water temperature regulation system is established according to the working principle of the high temperature fresh water cooling system. Secondly, the aforementioned system is chosen as the research object and a neuron-based adaptive control system is applied to regulate the temperature of cooling water. According to the algorithm of the control...
