Biography

Chen Hanfu, male, Han nationality, was born in Hangzhou and is a native of Shaoxing, Zhejiang Province. He graduated from Leningrad University in 1961.

Chen Hanfu has long observed random systems and status estimations of not using the initial value and giving optimal random singularity control. In the 1980s, Chen studied system identification, adaptation control and random approaches. He came up with the convergence velocity of common identification algorithms and estimated the parameters of closed loop control system. Chen used a disturbance method to make estimated parameters come close to their real value, and at the same time, made performance indices close to their optimization.

With regard to stochastic approximation, Chen put forward boundary variation truncation algorithms and introduced definite direct analytical methods. He removed the restrictive conditions to regression functions and lowered the noise requirements to the minimum, making the application scope of stochastic approximation greatly expanded. Chen also successfully applied these innovations to such fields as random adaptation ballast control, wide range of optimization and dynamic system of discrete events.

Chen is an expert on automatic control theory.
