However, the operation of such systems would be very poor, if possible at all, if the computer’s decision making programs were not being supplied with suitable, up to date, quality information about the state of the external system.
但是，如果没有为计算机的决策程序提供有关外部系统状态的适当的最新质量信息，那么，如果可能的话，此类系统的操作将非常糟糕。
Electrical noise (i.e. unwanted signals) may be generated by variation in contact resistance, by mechanical wear due to contact fiction, and by contact vibration transmitted from the sensing element.
电噪声（即不需要的信号）可能由接触电阻的变化、接触摩擦引起的机械磨损和传感元件传输的接触振动产生。

Actuators are basically the muscle behind a mechatronics system that accepts a control command (mostly in the form of an electrical signal) and produces a change in the physical system by generating force, motion, heat, flow, etc.

正常情况下，由于弹簧力的作用，软铁心被推到最左边的位置；当电磁阀被激发时，软铁心会移动到最右边的位置，从而提供电磁驱动。
A/D conversion is essentially a quantizing process, whereby an analog signal is represented by discrete states.
A / D转换本质上是量化过程，通过这个过程将模拟信号用离散状态表示。
An A/D converter requires a certain amount of time, called conversion time, to change an analog signal into the corresponding digital signal. If the analog signal changes during the conversion time, the converter output may be in error. To prevent this, a sample-and-hold circuit is used to sense the analog signal at the start of conversion, and store it on a capacitor during the remaining conversion time.
A/D转换器需要一定的时间（称为转换时间）将模拟信号转换成相应的数字信号。如果在转换期间模拟信号发生变化，则转换器输出可能出错。为了防止这种情况，在转换开始时使用采样保持电路来检测模拟信号，并在剩余的转换时间内将其存储在
电容器
上。

As a result, rudimental control systems were developed. Relays were attached to the instruments so that processes could respond to parametric changes. Soon, the single relay grew into more than one, allowing for multipoint control. Then, rate detectors were added and finally integrators, creating the PID control system.

It became normal for a measuring instrument to accept a signal; condition the input by linearizing, shaping, band limiting, etc.; and then digitize the result. The digital output was manipulated in a special, onboard processor in order to provide control or analytical decisions.
测量仪器接收信号变得正常；通过线性化、整形、频带限制等调节输入；然后将结果数字化。数字输出在一个特殊的机载处理器中进行操作，以提供控制或分析决策。
At the same time, the sphere of measurement and control systems expanded from merely measuring electrical and electronics parameters to encompassing all ancillary technologies including the mechanical, chemical, civil, and medical fields.

The definition of the transfer function requires the system to be linear and stationary, with continuous variables and with zero initial conditions. The transfer function is most useful when the system is also lumped parameter and when transport lags are absent or neglected.

第一篇: Observations of offshore wind characteristics by Doppler-LiDAR for wind energy applications
原文
译文
The interest of investigating offshore wind characteristics is receiving growing attention worldwide, which mainly attempts to boost the development of offshore wind energy and accelerate sustainable development. In particular, the understanding of offshore wind characteristics at the hub heights of wind turbines is of great significance in regard to the assessment of economic feasibility and structural design of wind turbines. Since traditional meteorological masts have limitations in height due to economic and technical considerations, remote sensing techniques have increasingly been employed for offshore wind observations.
海上风电特性的研究在世界范围内受到越来越多的关注，其主要目的是促进海上风能的开发和促进可持续发展。特别是了解风电机组枢纽高度处的海上风特性，对于评估风电机组的经济可行性和结构设计具有重要意义。由于传统的气象桅杆由于经济和技术上的考虑，高度受到限制，遥感技术越来越多地应用于海上风场观测。
This paper presents a comprehensive assessment of offshore wind characteristics on the basis of measurements from a light detection and ranging (LiDAR) system at an offshore site in Hong Kong. The fidelity of the wind LiDAR measurements was firstly examined by comparing with those obtained from anemometers on a nearby meteorological mast. Statistical analysis of wind speed was performed by means of the Weibull distribution function, and the results were subsequently used to facilitate the determination of several characteristic parameters associated with wind energy applications. The vertical profiles of wind speed derived from the LiDAR system were compared with existing models. Characteristics of wind shear coefficient were examined within different height ranges. Furthermore, the offshore turbulence characteristics were investigated, including the turbulence intensity and gust factor. The outcomes of this study are expected to provide useful information for the development of offshore wind energy.
本文基于香港近海光探测和测距（LIDAR）系统的测量结果，对海上风场特性进行了综合评价。通过与附近气象桅杆上风速计的测量结果进行比较，首次检验了测风激光雷达测量结果的保真度。利用Weibull分布函数对风速进行统计分析，结果随后用于确定与风能应用相关的几个特征参数。从激光雷达系统得到的风速垂直廓线与现有模型进行了比较。研究了不同高度范围内的风切变系数特征。此外，还研究了近海湍流特性，包括湍流强度和阵风因子。本文的研究成果有望为海上风能的开发提供有益的参考。

第三篇: Mastering the game of Go with deep neural networks and tree search
原文
译文
The game of Go has long been viewed as the most challenging of classic games for artificial intelligence due to its enormous search space and the difficulty of evaluating board positions and moves. We introduce a new approach to computer Go that uses value networks to evaluate board positions and policy networks to select moves. These deep neural networks are trained by a novel combination of supervised learning from human expert games, and reinforcement learning from games of self-play. Without any lookahead search, the neural networks play Go at the level of state-of-the-art Monte-Carlo tree search programs that simulate thousands of random games of self-play. We also introduce a new search algorithm that combines Monte-Carlo simulation with value and policy networks. Using this search algorithm, our program AlphaGo achieved a 99.8% winning rate against other Go programs, and defeated the European Go champion by 5 games to 0. This is the first time that a computer program has defeated a human professional player in the full-sized game of Go, a feat previously thought to be at least a decade away.
围棋由于其巨大的搜索空间以及棋盘位置和动作的评估难度，一直被视为人工智能领域最具挑战性的经典游戏。我们提出了一种新的计算机围棋方法，它使用价值网络来评估棋盘位置，使用策略网络来选择移动。这些深层神经网络是由一种新的组合训练的监督学习从人类专家游戏，并加强学习从游戏的自我发挥。在没有任何前瞻性搜索的情况下，神经网络发挥了最先进的蒙特卡罗树搜索程序的水平，模拟数千个随机游戏的自我发挥。我们还介绍了一种新的搜索算法，将蒙特卡罗模拟与价值和策略网络相结合。使用这种搜索算法，我们的程序AlphaGo在与其他围棋程序的比赛中获得了99.8%的获胜率，并以5比0击败了欧洲围棋冠军。这是计算机程序第一次在全尺寸围棋游戏中击败人类专业玩家，这一壮举此前被认为至少还有十年的时间。
