Academician Jason, President of Shanghai Jiaotong University, called Zhang "a leading figure in the field of control in China" and "a model and model of intellectuals in the new period" in the preface to the commemorative book.
This album comprehensively records the commemorative activities held by Shanghai Jiaotong University, introduces Mr. Zhang's life in detail, and reflects his important contribution to the field of automatic control and system engineering in China. It reviews Mr. Zhang's activities with rich pictures and materials, and shows Mr. Zhang's outstanding talent, scientific demeanor, noble character and warm affection through comprehensive discussion and memories from colleagues, friends, students and relatives.
1965438+In September 2005, Zhang was born in an ordinary teacher's family in Jiashan, Zhejiang, and left home to study at the age of1/kloc-0. As a teenager, he was outstanding, knowledgeable, memorable, quick-thinking, and had a wide range of interests. 1September 1930, 15-year-old Zhang was admitted to the School of Electrical Engineering of Jiaotong University with excellent results. 1934 graduated, that is, he won a scholarship from the China-US Cultural Education Foundation with excellent academic performance, entered the Department of Electrical Engineering of Massachusetts Institute of Technology, and obtained a master's degree two semesters later. Five semesters later, he got a doctorate in science.
During his study at MIT, Zhang boldly applied Fourier series originally used in astronomy to the dynamic equation of single-phase motor short circuit problem. After careful argumentation and ingenious reasoning, he obtained a mode constant of this kind of motor for the first time in theory, and his doctoral thesis "Short Circuit Analysis of Single-phase Motor" was highly praised. He also became the first postdoctoral associate researcher since the establishment of 186 1 MIT.
1938, Japanese invaders set foot in East China. At the age of 24, Zhang's blood was boiling. /kloc-returned to Hong Kong on 0/0, and successively served as a professor in the Department of Electrical Engineering of Wuhan University, Central University and Jiaotong University. He taught students advanced electrotechnics mathematics, telecommunication network and other courses, guided students to engage in the research of network synthesis theory, wrote the world's first monograph on network synthesis theory, and began to study automatic control theory.
After the liberation of Shanghai, the power grids in the former concession were all independent, and the output voltage and frequency of each power plant were different. In order to manage the city's power supply in a unified way, Zhang led the power grid merger, transformed some generator sets and unified the voltage and frequency. Then he suggested that cadres should be transferred to organize power dispatching training courses to train power management talents.
In 1973, Zhang and some colleagues organized a discussion class to solve the inertial navigation of submarines. He taught modern control theory and compiled the book Matrix Method and Modern Control Theory, which became the earliest modern control theory work in China. After two years of hard work, the navigation problem has been solved perfectly.
Near ancient times, Zhang is also in charge of the long-term development planning consulting project of Xinjiang Uygur Autonomous Region accepted by Shanghai Jiaotong University. He led an investigation team into Xinjiang, established a dynamic economic control model and completed an affiliated Delphi expert consultation system. This model enables people to obtain various economic indicators that Xinjiang can achieve from 1990 to 2000 through computer simulation, describe the prospect of Xinjiang in 2 1 century, and find potential problems. This model is also the first large-scale regional socio-economic model established in China with the idea of systems engineering. This research won the Shanghai Science and Technology Achievement Award.
From 65438 to 0985, Zhang resigned from all administrative positions of Shanghai Jiaotong University, but he served as a consultant professor or honorary professor and honorary president of 23 universities across the country. He also served as a senior scientific and technological consultant in Xiamen Special Economic Zone, Changshu and Jiaxing, and made suggestions for economic and technological development.
Perhaps it was my early work experience in Shanghai Public Utilities Bureau. Zhang has always been concerned about the development of management science. From 65438 to 0977, he put forward the idea of popularizing system engineering in China at a national academic conference held in Guangzhou, and became one of the earliest scientists who advocated the system engineering method in China. Around 1980s, Zhang and other scholars put forward a new generation of economic cybernetics.
1984 Zhang put forward the theory of industrial large-scale system under the guidance of large-scale system theory and the application of microcomputer as the breakthrough point, forming hierarchical distributed computer control and information management, referred to as "one big and one small" for short. He discussed the basic functions of microcomputer application in control, and put forward new research topics such as computer communication and computer coordination. In the following ten years, Zhang participated in publishing hundreds of papers, covering almost the whole automation field. In the process of automation development in China, Zhang is not only a pioneer, but also an academic leader who always fights at the forefront.
