Recently, the General Office of the Ministry of Education issued the "Ministry of Education Award for Outstanding Scientific Research Achievements (Science and Technology) in Higher Schools in 2020 "Decision of the People’s Republic of China", the research result "Networked Control Switching System Processing Method" led by Professor Yu Li from the School of Information Engineering of Zhejiang University of Technology won the First Prize of Natural Science of the Ministry of Education.

With the rapid development of network technology, the control system is also developing towards networked intelligence, becoming an important part of the industrial Internet . Network uncertainties such as information transmission delay, packet loss , and timing disorder caused by networking have seriously affected the performance of the control system with high-speed and high-precision control goals, and sometimes even led to system instability.

The "Industrial Internet and Security" innovation team led by Professor Yu Li has undergone in-depth research for nearly 20 years, and the result "Networked Control Handover System Processing Method" has analyzed the impact of communication uncertainty on system performance and established Based on the quantitative relationship between network characteristic parameters and system performance, a collaborative design method for network scheduling and control is proposed, and a set of theories and methods for modeling, analysis and design of networked control systems based on switching system processing methods are formed to solve control problems in the future The network uncertainty problem brought about by the system has opened up a new path.

According to the team leader Professor Yu Li, the research results proposed in this study, such as the processing method of the networked control system switching system, the quantitative relationship between network parameters and system performance, have been highly evaluated and popularized by domestic and foreign counterparts. The networked motion controller developed by this achievement has also been industrialized.
