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

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。

For this subject, I think that the quality of students depends on their own environmental factors. In today's world economic competition with the rapid development of science and technology and the increasingly fierce international competition, the competition of comprehensive national strength is essentially a national science and technology competition, and the quality competition who masters the education of the century will be able to take the strategic initiative in the international competition in the 21st century Status, the quality of students and the development of the country is inseparable, so only from all aspects to improve their own quality in order to have a good development.

对于这个课题，我认为学生自身素质的高低取决于其自身的环境因素，在当今世界科学技术飞速发展、国际竞争日益激烈的世界经济竞争中，综合国力的竞争本质上是一个国家的科技竞争而素质竞争谁掌握了世纪教育，谁就能够在21世纪的国际竞争中处于战略主动地位，学生的素质与国家的发展是分不开的，所以只有从各个方面提高自身素质才能有好的发展。

满分英语范文3：科技发展快

I want to invent a time machine. If I have the ability to invent something that can make life better, the first thing I think about is that with the help of time machine, people can easily go back to the past. We will inevitably make some mistakes that we regret very much.

If we can get another chance to repair it, it will be great for the elderly, if they can It's a very important dream to be young again. Although it sounds like an impossible dream, I still believe that with the rapid development of science and technology, my idea will become a reality one day. The first thing easy to think of is to be able to achieve the rapid development of science and technology.

中文翻译：

我想发明一台时间机器，如果我有能力发明一些能让生活变得更好的东西，首先想到的是时间机器在它的帮助下，人们可以方便地回到过去我们不可避免地会犯一些我们非常后悔的错误，如果我们能再得到一个机会来修复它，那就太棒了对老年人来说，如果他们能够再次重获青春，这是一个很重要的梦想，虽然这听起来是一个不可能实现的梦想，但我仍然相信，随着科学技术的飞速发展，我的想法总有一天会成为现实，第一件容易想到的事就是能够做到随着科学技术的飞速发展。
