- Considered the relationship between the dirac structures of poisson - nijenhuis manifold and the basic vector field , we proof that the basic vector field can keep the dirac structures of poisson - nijenhuis manifold which discussed before
考虑了基本向量场与dirac结构的关系，在前三节的基础上证明了基本向量场可以保持上述李双代数胚上的dirac结构。 - The last , we study the properties of the basic vector field and 1 - form in the poisson - nijenhuis manifold , making a systematic organization of these contents and giving some appropriate adds . therefore , we unified with the conclusion of the poisson vector field on poisson manifold in reform
最后我们研究了poisson - nijenhuis流形上基本向量场和基本1 -形式，对已有的成果进行了系统的整理，并加以补充。由此将poisson - nijenhuis流形上基本向量场和泊松流形上的泊松向量场从形式上得到了统一。 - The feasibility of decomposition of transition firing sequence , the application of them in the detecting lfs and the reverse course of decomposition - synthesis are discussed . they provide theoretic basis for our algorithm in the field of petri net . supported by the above , two main part is included in the algorithm : at first , x is transacted according to the following method in order to get a set of xb named as basic vector of x which is the firing count vector of a directed path without circle if md is reached from m0 in the rg ( m0 )
在变迁序列分解的指导思想下，我们的算法主要通过以下两步工作完成： ( 1 )首先对给出的已知条件中满足状态方程的n维非负整数向量进行处理，得到一组x的基础向量x _ b ，使得在petri网的可达标识图中，若存在一条由m _ o到m _ d的有向无环路，则x _ b为这样的路上变迁引发序列的发生数向量。 - 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。
