In the afternoon of April 16, 2021，IEEE PES Day 2021 preaching session was held at Xinglongshan Campus of Shandong University，The theme of this lecture is Clean Energy Revolution。IEEE PES Day Ambassador、Professor Lu Tianguang, a professor at the School of Electrical Engineering, Shandong University, presided over the event，There are also professors at the School of Electrical Engineering of Electrical Engineering of Shandong University, Teacher Ye Hua, and IEEE PES Day Student Ambassador Si Zhiyuan and the School of Electrical School 2017、2018 undergraduate。

For the topic of this lecture，Special invitation Teacher Ye Hua communicated with everyone based on his own experience and scientific research experience。Teacher Ye Hua first introduced his own research work experience and experience，His educational work experience、Talent Team Platform、Introduction to the four aspects of scientific research academic contribution and research work experience，Combining your own personal experience tells how to find problems in scientific research，Learn to innovate and solve problems，He pointed out that learning must first lay a solid foundation，To study the work made by the predecessors，Thinking hard on this basis，Learn to turn impossible into possible，Perseverance can only learn something。Teacher Ye recovers the idea of ​​the optimal control of the middle of the slump horn through the example system、Division of zero -damping free response and positive damping resonance，Show the students to find a problem、Analysis of problems and methods to solve problems，Everyone is vividly image by Teacher Ye、The in -depth explanation is convinced。Teacher Ye tells you a few experiences in scientific research work，The first is the in -depth understanding and comprehensive application of basic knowledge，The second is to track research+diligent thinking+timely breakthrough，Third is to establish a big goal+persistent firm belief。Teacher Ye also made a proposal for the study and scientific research of the students，Expressing ardent expectations。Last，Teacher Lu Tianguang andTeacher Ye Hua learn to learn about basic knowledge、The contradictions between learning knowledge and exam -oriented examinations have been discussed.，Answer the doubts of the students，Encourage students to continue learning，Make full use of extracurricular resources to obtain more knowledge。Students expressed their benefits after listening，Express the teacher for the teacher with warm applause。
