高分英语作文1：Understand the development of science and technology

The century is the century of science and technology. Science and technology are everywhere. The development of science and technology has a great impact on the society.

The Internet, computers and mobile phones are the common technologies we use. These new technologies make our life easier and better. Decades ago, the development of computers changed our life.

Without computers, people need to do many complicated things in their hands Computing, more obviously, they don't have computing software. Since the development of computers, people have spent several hours on equations that can be solved in one minute. People can use some software to calculate many complex functions, and mathematical computing computers have become the most useful equipment for scientific workers, because they can make more effective use of time.

The Internet is us Today's another useful tool, the development of the Internet has brought great influence to the society. Instead of going to the library to search all the books to find some information, we just need to click the website with the mouse to study. The Internet has brought us to a place where we can find unlimited information and resources, which makes our life easier and better.

The last technology now is mobile phones. Now, many people have a mobile phone, but it's only been on the market for a few years, which is very convenient for users, because we can talk to anyone on a phone as small as a wallet, and we can communicate with others by calling instead of writing letters. In short, this is a very fast and useful way of communication.

I believe that the development of science and technology will have a significant impact on our lives, which is very helpful to us. I believe that technology will continue to improve in the future, and I hope it can help us to be safe.

世纪是科技的世纪，科技无处不在，科技的发展对社会产生了重大的影响，我们通常使用的几种技术是互联网、电脑和手机这些新技术使我们的生活变得更加轻松和美好，几xx年前，计算机的发展改变了我们的生活，因为没有计算机，人们需要在手上做许多复杂的计算，更明显的是，他们没有计算的软件，自从计算机的发展，人们花了好几个小时在一分钟内就能解出的方程组上，人们能够用某种软件来计算许多复杂的函数，而数学计算计算机则成为科学工作者最有用的设备，因为他们可以更有效地利用时间，互联网是我们今天的另一个有用的工具互联网的发展给社会带来了巨大的影响，而不是去图书馆翻所有的书来找出一些信息，我们只需简单地用鼠标点击网站进行研究互联网把我们带到了一个可以找到无限信息和资源的地方，它使我们的生活变得更加轻松和美好。现在的最后一项技术是手机。现在，许多人都有一部手机，但它只在市场上出现了几年，这对用户来说非常方便用户因为我们可以用一个像钱包那么小的电话和任何人交谈，我们可以通过打电话而不是写信来与其他人交流。

总之，这是一种非常快速和有用的沟通方式，我相信科技的发展会给我们的生活带来重大的影响，这对我们很有帮助，我相信科技在未来会不断进步，我希望它能帮助我们安全。

今天父亲带我去了科技中心我很喜欢发明我知道科技是人类进步的最大动力，有一位翻译向我们解释了这些发明的过程，我看到了许多以前从未见过的飞机和卫星模型，这对我来说真是一个令人大开眼界的日子。

满分英语范文3：了解科学技术的发展

With the rapid development of modern science and technology, the importance of control theory and technology is increasingly prominent. Control technology is widely used in metallurgy, petrochemical, machinery, food, pharmaceutical, aerospace and military systems. In other fields, helicopter three degree of freedom control system is a typical high-level, unstable, multivariable, nonlinear, strong coupling control system The modeling, design and Simulation of the system can promote and deepen the application research of control theory and technology in complex control system.

Many modern control theory researchers will study its target, but the control effect is not ideal. The main reason is that the system is high-order and multivariable to solve the balance control problem of helicopter control system based on state space The optimal regulator LQ is designed to balance the robustness and speed of the system. In this paper, the composition of the helicopter is analyzed, and then the mathematical modeling of its pitch angle is carried out.

The state equation of the system and the effectiveness of the system are introduced. On this basis, the system architecture model is established for simulation in the MATLAB / Simulink environment. Finally, the LQ controller is designed.

Googoltech uses the GHP general control card to establish matlab sequence or control toolbox The LQ control system of pitch angle is constructed to realize the real-time control of helicopter pitch angle.

随着现代科学技术的飞速发展，控制理论和技术的重要性日益凸显，控制技术广泛应用于冶金、石油化工、机械、食品、制药、航空航天和军事系统中，从其他领域来看，直升机三自由度控制系统是一个典型的高水平、不稳定、多变量、非线性、强耦合的控制系统，对系统进行建模、设计和仿真，能够促进和深化控制理论和技术在复杂控制系统中的应用研究许多现代控制理论研究者都会对其目标进行研究，但其控制效果并不理想，主要原因是系统的高阶性和多变量性，以解决直升机控制系统的平衡控制问题，基于状态空间设计最优调节器LQ，较好地平衡了系统的鲁棒性和速度。本文分析了直升机的组成，然后对其俯仰角进行了数学建模，介绍了系统的状态方程，系统的有效性，然后以此为基础，在MATLAB/SIMULINK环境下建立系统架构模型进行仿真，最后进行LQ控制器的设计，GoogolTech利用GHP通用控制卡建立Matlab序列或控制工具箱，在Simulink环境下构建俯仰角LQ控制系统，实现直升机俯仰角的实时控制。
