Moreover, the mean-square tracking error can be made arbitrarily small by choosing some design parameters appropriately. Even with unmodeled dynamics and bounded disturbances presented the controller has good robust performance without need of correct dynamic model and parameter estimation.
并且这种控制器的设计不需要有精确的系统动态模型,不需要未知参数来满足线性依赖条件,不需要具体的系统参数估计,即使存在未建模动态和有界扰动,系统仍然具有很好的鲁棒性。

We have proposed the switching adaptive control law for the systems and designed the Lyapunov function in this thesis. It is proved that the proposed switching adaptive control law guarantees the solutions of the nonlinear systems boundedness and convergence of the tracking error to a residual set based on the Lyapunovs stability theory. The residual set can be made arbitrarily small by choosing a certain design parameters.
文中设计出了这类系统的切换自适应控制律,并构造出相应的Lyapunov函数,基于Lyapunov稳定性理论证明了系统在所设计的控制律作用下,闭环信号都有界并且跟踪误差收敛到一个集合,通过选择适当的参数可使这个集合任意小。

It is shown that under the supervision of the monitoring functions, the switching of control signal will stop after a finite number of switching and the tracking error will converge to a residual set that can be made arbitrarily small by choosing some design parameters sufficiently small.
进而证明,当被控对象相对阶大于1、高频增益符号未知时,在监控函数的监测下,相关控制信号经至多有限次切换后将停止切换,跟踪误差将收敛到一个残集内,且该残集可通过减小某些设计参数而变得任意小。

Married when she was just 17 years old, Isabel balances Alex by choosing not to involve herself in the business, focusing instead on their three children, Jaime, Katie and Artie, who are determined to forge their own paths outside the family. Jaime has a deep love for his father but also yearns to go his own way.

The paper draws the following conclusions:Brand value is the evaluation to the brand as asset and equity and it can be expressed as brand financial value and brand equity. Brand value comes from the extra utility it takes to the customers by satisfying their special needs. The forming base of the brand value is closely relative to the customers, and there are some other factors infecting brand value such as brand extension. Brand value evaluation includes two parts. One is to have a valuation to the brand financial value, the other is to evaluation of the brand equity by choosing a suitable brand equity model.
经过上述研究,本文得到以下结论:品牌价值是对品牌作为一种资产和一种权益的价值量化,具体体现为品牌财务价值和品牌权益价值;从效用价值论的角度,品牌价值来源于品牌带给消费者的特殊效用;品牌与消费者的关系是品牌价值的形成基础,品牌价值的大小还要受到其他因素的影响;完整的品牌价值测评应由两方面构成:按照收益法原则测评品牌的财务价值;选择适当的品牌权益模型对品牌权益进行测评。

Choosing time delay as the control parameter, the stability of trivial equilibrium is discussed by analyzing distribution of the roots of the associated characteristic equation. It is found that Hopf bifurcation occurs from trivial equilibrium when the delay passes through critical values, then the critical values and their relations with system control parameters are obtained.
以时滞量为参数,通过分析对应线性系统特征方程的根的分布,讨论了平凡解的稳定性,得到了平凡解发生Hopf分岔而失稳的临界时滞量以及临界时滞量与系统控制参数的关系。
