动态结构
Examples
- In this paper the tendency of motion control is introduced first . next the basic vector control principle and coordinate transformations are presented . the mathematic model and the equiva1ent circuit of induction motor are also proposed . on the basis of the former theory a dynamic structure of sensorless vector - controlled system is designed here . a new flux observer and a new method of speed estimation are put forward also . and then the model of the control system is established . following those , the author simulates the dynamic 2 system using the advanced language c + + and analyzes the result
本文首先介绍了交流传动的发展动向，接着阐述矢量控制基本原理、坐标变换和异步电机数学模型及其等效电路。在此基础上，本文设计一种无速度传感器矢量控制系统动态结构，应用状态估计与状态观测器理论，提出了新型磁通观测器结构和速度推算方法，对控制系统建立数学模型，用c + +语言进行动态仿真，并对结果进行理论分析，通过仿真实验证明方案的有效性和正确性。 - The wavelet multi - analysis is adopted to further understand the microstructure of solids holdup fluctuation , the vivid fingermark images show that it is a fractal and dissipative structure . the low and frequency signals reflect the dilute phase fluctuation behavior and dense phase ( cluster ) fluctuation behavior , respectively . to deep understand the multi - scales characteristic of gas - solids circulating fluidization , the wp decompose methods for obtaining the eigenvalue of gas - solid fluidized bed has been developed . the results show that eigenvalues of different scales are effective for identification of non - uniform and dynamic structure of gas - solid fluidized bed
