高分英语作文1：Advantages and disadvantages of modern science and technology
Advantages and disadvantages of technology although technology has many advantages and disadvantages, the main reason for inventing things is to make the task easier to perform. Technology makes the task easier, faster, more efficient and better. On the other hand, technology can make people more lazy, and the production cost of products is lower (this is good for the company, but not for consumers, and technology may be for human health and safety) Adverse effects.
中文翻译：
技术的优点和缺点尽管技术有许多优点和缺点，但发明事物的主要原因是为了使任务更容易执行技术使任务更容易、更快、更高效、更好；另一方面，技术可以使人更懒惰，产品制造成本更低廉（这对公司有利，但对消费者不利，而且技术可能对人的健康和安全产生不利影响。
万能作文模板2：现代科学技术的利弊
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。
