高分英语作文1：Modern science and technology

Everything has two sides. Modern technology also has its advantages and disadvantages. First of all, it makes our life more convenient.

For example, the bus saves us a lot of time. It provides us with safer food, just like "green food". In addition, it makes us know more about human beings and the earth.

However, it also pollutes us. Tooit also makes some of us lazy because life is too comfortable. First of all, we should make full use of technology and do our best to help the earth and people: eed.

任何事物都有两面性现代科技也有它的优点和缺点首先它使我们的生活更加方便例如，公共汽车节省了我们很多时间，它提供给我们更安全的食物，就像“绿色食品”一样。此外，它使我们对人类和地球有了更多的了解，然而，它也带来了污染我们，tooIt也让我们中的一些人变得懒惰，因为生活太舒适了首先，我们应该充分利用科技，尽我们所能帮助地球和人们：eed。

万能作文模板2：现代科学技术

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。

满分英语范文3：现代科技

The continuation of human life is inseparable from science and technology. Human society develops with the progress of science and technology, and the development of science and technology in turn brings process to human beings. Therefore, our life is more civilized than our ancestors.

The development of science and technology has brought many changes to people's life, such as the invention of television and space rocket In the new era, due to the invention of spaceship and rocket, people can hear the sound and understand the events that happened thousands of miles away. Now the dream of landing on the moon has come true. Science and technology also plays an important role in our socialist construction.

We can say that our socialist construction is like a skyscraper, and science and technology are its foundation. Without foundation, mo Therefore, we should try our best to contribute to our socialist construction, develop science and technology, and provide a more solid foundation for the construction of our country.

人类生命的延续离不开科学技术，人类社会是随着科学技术的进步而发展的，而科学技术的发展反过来又给人类带来了过程，所以我们现在的生活比我们的祖先更加文明；科学技术的发展给人们的生活带来了许多变化，例如电视和太空火箭的发明为人类打开了一个新时代，由于宇宙飞船和火箭的发明，人们可以听到声音，了解千里之外发生的事件，人类登月的梦想现在实现了，科学技术在我们的社会主义建设中也起着重要的作用我们可以说，我们的社会主义建设就像一座摩天大楼，而科学技术是它的基础，没有了基础，摩天大楼是不可能建成的，因此，我们应该尽最大努力为我们的社会主义建设作出贡献发展科学技术，为建设我国提供更坚实的基础。
