 As the parameters of a nonlinear Takagi-Sugeno(T-S) fuzzy control system are perturbed by random noises with known covariance matrix, the system turns to be a stochastic T-S system. 设控制对象是用Takagi-Sugeno(T-S)模糊模型表示的非线性系统,当模型参数受到统计特征已知的随机噪声干扰时,就成为一个随机T-S模糊模型,本质上它是一个非线性随机系统。 短句来源 The comparative results of R6D,R5D and four degree of freedom model (4D) under identical conditions indicate that R5D is a good compromise mode[ between R6D and 4D. The mathematical fundamentals for the formation of R5D are briefly discussed. 文中给出了相同条件下R6D,R5D及四自由度模型(4D)的比较结果,表明R5D是R6D与4D间的一个好的折衷模型,并简要论述了R5D的实现方法的数学本质上的合理性。 短句来源 In this paper, We discuss relation between bouncing ball mapping and Taylor mapping, and prove that bouncing ball mapping for α= 1 is the same as Taylor mapping for n = 1 in the nature. Then using this result, we obtain conclutions as follow: (i) when r>2.5n , bouncing ball mapping for α= 1 has chaos behavior, (ii) when A≥4.27π , Taylor mapping for n = 1 exists chaos set with hyperbolic structure. 本文研究了弹跳球映射和Taylor映射间的关系,指出α=1的弹跳球映射与n=1的Taylor映射在本质上是一致的,然后利用此性质推出:α=I,r>2.5π的弹跳球映射有浑沌现象,而n=1,A≥4.27π的Taylor映射其浑沌集具有双曲结构。 短句来源 The mathematical definition for the fuzziness in TFA is given. Some necessary survey rules and indexes are defined. For the application, we propose the concept of fuzzy point on time-frequency surface, and use the concept to reprocess the Wigner distribution to make the WD pictures clearer and more audio-visual for the interpretatoin. 从时频分布概念的局限性出发，提出的时频分布本质上是个模糊概念的观点．将模糊集的概念和方法引入时频分析，建立了时频分布模糊性的规范化定义、相应的测度指标和操作规则．在此基础上进一步引入时频域上模糊空间的概念，将此概念用于对Wigner分布的分析和再处理具有良好的效果． 短句来源 As linear time delay systems are infinite dimensional in natural, some new sufficient conditions in Riccati equation form are offered, which extends current related results. 受限于线性时滞系统本质上的无限维性，现已取得的有关线性时滞系统的H∞控制的结果较之不含时滞的线性系统，还是较少的。 对上述两类时滞系统，我们得到若干Riccati方程形式的充分条件，推广了现有成果。 短句来源 更多 查询“本质上”译词为用户自定义的双语例句

Starting from the fundamental equations of electric machine, this paper develops an analytic method of investigation of the self-excitation problem of asynchronous machine connected through series capacitor. Constant synchronously rotating system components dc and qc and method of small oscillational equations are used ia the analysis; steady state oscillational principles, spectrum frequency analysis of discri-minating occurrence of self-excitation are discussed. Correlation between these methods are also described. Results obtained from this theoretical analytic method are compared with those obtained from experimental tests, the agreement between them is very close. It is found that the basic nature of self-excitation phenomenon of asynch-ronous machine, as shown from the results of this investigation, is a kind of resonance among the electro-mechanical parameters of the machine. Traditional methods of analysis, being used so far by many writers, regarding the speed of the machine as a constant factor, cannot reveal the effect of rotational inertia of the machine upon the self-excitation process. 本文从电机基本方程出发,介绍了与串联电容相联的异步电动机的自激区的分析方法。分析中利用了同步恒速转动坐标系统d_c,q_c分量及其微干扰方程式;同时还讨论了稳态小值振荡理论、判别自激的频率法和这些方法的内在联系。理论分析所得结果与实验数据相当一致。研究结果表明,异步电机的自激本质上是一种机电参数共振现象,过去惯用的把电机转速视为恒值的方法不能反映电机惯性常数等因素对自激的影响。 In order to formulate the equations for the study here, the Fourier expansions upon the system of orthonormal polynomials are used. It may be considerably convenient to obtain the expressions of displacements as well as stresses directly from the solutions. Based on the principle of virtual work the equilibrium equations of various orders are formulated. Particularly the system of third-order is given in detail, witn a result to provide the reference for accuracy analysis of lower order equations. A theorem... In order to formulate the equations for the study here, the Fourier expansions upon the system of orthonormal polynomials are used. It may be considerably convenient to obtain the expressions of displacements as well as stresses directly from the solutions. Based on the principle of virtual work the equilibrium equations of various orders are formulated. Particularly the system of third-order is given in detail, witn a result to provide the reference for accuracy analysis of lower order equations. A theorem about the differentiation of Legendre Series term by term is proved as the basis of mathematical analysis. Therefore the functions used are specified and the analysis rendered is no longer a formal one. The analysis will show that the Kirchhoff-Love's theory is merely of first-order and the theory which includes the transverss deformation but keeps the normal straight is essentially of first-order, too. 利用正交多项式系上的Fourier展开就容易由方程的解直接得到位移和应力的明确表示.从薄壳的虚功原理出发导出各阶平衡方程.作为数学分析的基础,证明了关于Legendre级数逐项求导的定理.从而明确了对函数的要求,分析便不再只是形式的了.具体给出了三阶近似的平衡方程,可供对低阶近似的精度分析作参考.分析说明直法线理论只能是一阶的近似,法线无伸长地倾斜的假设本质上也是一阶的近似. In engineering practice thereis not any sharp dividing line between the"Success" and the "Failure" for the situationof system or part generallY, And there oftenbe many models and states onthe"Failure".effects of models and dividing lines ofstates are not completely distinctness too.For this reason, the reliability is a fuzzyconcept intrinsically. In view of this fact,his article, basing on the fuzzy mathematicsttheory, made a relatively systematic expo-sition of basic concepts and methods of fuzzreliability....

In view of this fact,his article, basing on the fuzzy mathematicsttheory, made a relatively systematic expo-sition of basic concepts and methods of fuzzreliability. Fuzzy failure, fuzzy reliability,fuzzy assessment and predictron for reliability,as well as fuzzy design for system reli-ability are discussed particularly and methodsproposed are illustrated by examples in thispaper. 在工程实际中,系统或元件状态的“完好”和“失效”之间一般不存在明晰的界线。而且“失效”往往有多种模式和状态,各种模式的影响和状态的界限亦不尽分明。因此,可靠性本质上是一个模糊概念。本文针对这一现实,运用模糊数学的理论,较系统地阐述了模糊可靠性的基本概念和方法。文中着重讨论了模糊失效、模糊可靠度、可靠度的模糊评价与预测,以及系统可靠性的模糊设计,并对所提出的方法以示例作了说明。 << 更多相关文摘 相关查询
