Although the compulsory sample collection of human body is one of important methods to find the truth in detecting the crime,it easily infringes upon civil rights such as the right of body,the right of personal freedom,the right of human dignity,the right of privacy and so on.

Circuit design of luminosity sampling for the spectrophotometer;

Reason analysis of deviation in sampling and preparation of commercial coal;

This system is based on the closed loop feedback principle,and it adopts a method which combines hardware closed loop with sampling control.

Characteristics and control process of a sampling controller is analyzed and methods of design for controller parameters and engineering tuning are described.

Ten years of the lifting technique for sampled-data control systems;

After discussing the sampled-data control over linear time-lag systems,and by using Lyapunov stability theory and linear matrix inequality approach(LMI),the authors have presented the criteria for identifying the existence of lag-dependent sampled-data law for controlling linear time-lag systems in LMI framework.

Sampled-data control theory offers theory guidance for computer control and design of sampled-data controller is a core problem of sampled-data control theory.
