随机控制

The stochastic Bonhoeffer-Van der Pol system is first transformed into an equivalent deterministic system using the Chebyshev polynomial approximation, so that the problem of controlling stochastic chaos is reduced to the problem of controlling deterministic chaos in the equivalent system.

首先运用Chebyshev多项式逼近的方法，将随机Bonhoeffer-Van der Pol系统转化为等价的确定性系统，使原系统的随机混沌控制问题转换为等价的确定性系统的确定性混沌控制问题，继而可用Lyapunov指数指标来研究等价确定性系统的确定性混沌现象和控制问题。数值结果表明，随机Bonhoeffer-Van der Pol系统的随机混沌现象与相应的确定性Bonhoeffer-Van der Pol系统极为相似。

The maximum principle of the optimal control for the stochastic systems described by Zakaj stochastic partial sifferential equationis proved by approximately minimum point theorem of E. Ekeland. The convexity and compactness of the set of control values is not assumed, and it is not necessary for the maximum principle about differentiability in control variables included in drift term of the stoch astic system and the integrand in index functional, and costate process satisfies the stochastic partial ...

在不假便定控制变量取值的集合是凸的和紧的，不要求随机系统的漂移项和指标泛函的被积函数关于控制变量具有可微性的情况下，用E，Ekeland的近似极小点定理证明了Zakai随机偏微分方程描述的随机系统的最优控制的最大值原理，和用很简洁的方法证明了协态过程满足一个随机偏微分方程。

Because elevator's movement is according to the floor and the sedan theater box calling signal, the traveling schedule signal carries on the control, but the floor and the sedan theater box's call is stochastic, therefore, the systems control uses the random logic control, namely, in realizes in elevator's basic control request foundation by the order logical control, According to the stochastic input signal, as well as elevator's corresponding condition, at the right moment controls elevator's movement.

由于电梯的运行是根据楼层和轿厢的呼叫信号、行程信号进行控制，而楼层和轿厢的呼叫是随机的，因此，系统控制采用随机逻辑控制，即在以顺序逻辑控制实现电梯的基本控制要求的基础上，根据随机的输入信号，以及电梯的相应状态，适时地控制电梯的运行。

To overcome the quadratic variation terms of stochastic control and the uncontrollability in chained system, a novel control design procedure is constructively proposed, which involves the introduction of a time-varying technique and the application of quartic Lyapunov function.

In the second reiew, the FDA examined the results of such a study. Known as study 3014, it was an unblinded, randomized, controlled trial comparing the incidence rates of hepatic, cardiac, and isual aderse eents in patients receiing Ketek and those receiing amoxicillin–claulanate.

在第二个审查阶段，FDA检查了一个被称为3014研究的研究结果。3014是一个非盲法，随机控制的实验，以比较使用Ketek以及使用阿莫西林克拉维酸复合制剂的患者的肝脏，心脏，视野的反面事件的发生率。

Then we searched MEDLINE, PubMed and CINAHL databases, using keywords "pelvic girdle pain and pregnancy" to find the published papers between 1996 and 2006. Afterward, manual searching was used to choose appropriate and randomized controlled trials research correlated to our topic.

以pelvic girdle pain和pregnancy为关键字，再利用人工阅读方式挑选出合适且为随机控制之临床试验(Randomized controlled Trials-RCTs)相关研究论文作为本文分析对象。
