Abstract Developed the system of data acquisition and feedback control on the basis
of serial communication, the computer can communicate with the DSP lock-in amplifier
and the control circuit at the same time from two serial ports. The system can read
data automatically and record the data by calling EXCEL. By real-time analyzing the
data, the program can send command to the control circuit of the manipulator so that
the fingers can adjust their action. It can reach the result of intelligent feedback
control. It is showed that the scheme is economical and reliable ，the system operates
stable, it can meet the challenge of the project.
