Biography

Guo Lei, male, Han nationality, is a native of Zibo, Shandong Province. He graduated from Shandong University.

Guo obtained a doctorate degree from the System Science Research Institute of the Chinese Academy of Sciences in 1987, and currently holds the position of researcher there. His scientific achievements include solving several basic theory problems in self-adaptation control, which includes random self-adaptation tracking, pole allocation and LQG control. Concerning the least-square self tuning regulator, Guo solved its stability and astringency, a problem that had puzzled the international control community for a long time. By introducing new ideas and methods, Guo established the estimation theory of a common nonequilibrium time-varying parameter system. He laid the stringent theoretical foundation of three types of track algorithms commonly used, including LMS, RLS and KF. With regard to "Feedback", the most basic concept in control theory, Guo put forward the theoretical framework of the basic problem, qualitatively studying "Maximum Capacity and Limit of Feedback Mechanism". As to several types of typical nonlinear uncertain dynamic systems, Guo achieved the critical value of feedback mechanisms coping with a maximum capacity of uncertainty.

Guo Lei was elected as an academician of the Chinese Academy of Sciences in 2001.
