润色如下内容：First of all, I have always been interested in electrical engineering and its automation field. I chose this major primarily because I developed a strong interest in circuits and the mysteries of electricity during my high school years. I wanted to understand how the power grid works and how impressive high-voltage power lines transmit electricity to every corner of the city, driving the operation of modern society. I graduated with a bachelor’s degree in Electrical Engineering and its Automation from Central South University. Through practical experiences such as laboratory experiments in courses like digital circuits, analog circuits, and electrical motor learning, I gained a deep understanding of the application of this major and accumulated rich practical experience and problem-solving abilities. For example, in the design of analog circuits, I simulated a small circuit using Multisim software. I felt proud and delighted when I controlled the components, switched the switches, and observed the response of the light or motor firsthand. Similarly, learning programming languages and applying them to practical projects, such as a food ordering system, made me feel the power of knowledge and the joy of practical application. In my postgraduate studies, I hope to apply my knowledge to the field of control engineering, especially learning more advanced control algorithms, further studying programming languages, and applying these algorithms in engineering practice (such as using better performance to control motors). This is why I choose to continue my studies.

From the perspective of the socio-economic situation, with the continuous advancement of technology, there is an increasing demand for automation control and intelligent systems in various industries. There are good job opportunities in technical teams of power grid or internet companies. In my future career planning, I hope that I can combine hardware and software and deeply consider how electrical engineering can apply intelligent technology to power systems to achieve more efficient and reliable power transmission.

I have been studying diligently and achieved good results in many important professional courses, such as Principles of Automatic Control (95), Analog Circuits (94), Principles and Applications of Microcomputers (92), Power Electronics Technology (95), and Electrical Motor Learning (91). My GPA has also been maintained at a high level, reaching 85.6, and I have consistently ranked in the top 15% of my class. I received a First-Class Scholarship (top 6%) and a Third-Class Scholarship during my sophomore and junior years, respectively. Additionally, I have excelled in classroom performance and received high praise from my teachers. I have consistently received good scores in class performance evaluations, reflecting my dedication to learning and outstanding performance. I am good at combining theoretical knowledge learned in class with practical applications to design feasible solutions. For example, I completed a project titled “MATLAB Simulation of Vector Control System for Asynchronous Motor Based on SVPWM” in the course of Motion Control Principles. This project comprehensively applied the knowledge of vector control principles of asynchronous motors in electrical motor learning, PID control methods learned in automatic control principles, and current loop and voltage loop control strategies learned in motion control principles. Through this project, I successfully integrated knowledge from multiple courses, deepening my understanding of electrical engineering and its automation field.

In terms of academic activities, I actively participated in undergraduate innovation and entrepreneurship competitions. In my freshman year, I participated in a university-level innovation and entrepreneurship project, which was a volunteer management system based on WeChat mini-programs. I received excellent results and completed the static design of related pages (volunteer information management page, team building management page, activity management page, etc.) and some dynamic jump functions. I also wrote part of the main app of the mini-program, including the app.js file, app.json file, and app.wxss file. During my sophomore year, I participated in a provincial-level research innovation and entrepreneurship project. The project was based on the application of visual recognition technology using OpenCV. I was responsible for paper writing and hardware testing. I used a C51 microcontroller and a Raspberry Pi core to test the motor control, drive the movement of the car, and complete the obstacle avoidance function of the unmanned driving intelligent vehicle. These activities not only deepened my understanding of practical technological applications but also enhanced my teamwork and problem-solving skills.

In addition to having excellent classroom performance and professional skills, I also focus on cultivating my learning attitude and abilities. I am diligent, serious, and hardworking, and have a strong thirst for knowledge. Moreover, I have strong self-learning abilities and have self-taught myself the use of Matlab and CAD software. I am adept at utilizing various resources and tools for in-depth learning and self-improvement. For example, in my graduation project, I built a photovoltaic power generation system (photovoltaic cells, buck circuit) using Simulink and verified the output characteristics of solar cells under different illumination conditions (such as uniform shading and partial shading), as well as the control of maximum power using different maximum power point control algorithms (such as perturbation observation method, incremental conductance method, particle swarm optimization algorithm, and its improved algorithm). I am also skilled in practical abilities and achieved good results in course design, receiving excellent grades. For example, in the course design of the design of a bidirectional interleaved DC/DC converter in the Power Electronics Technology course, I used a bidirectional DC/DC converter to construct voltage outer loop control and current inner loop control, thereby achieving voltage boost control and current control. In the Multisim-controlled car light course design, I used chips to implement special functions.
