According to the actual needs of course teaching of computer control technology,and the training of engineering students ＇ practical ability,a digital servo system was developed and TMS320F28335 was applied as controller. It applied genetic fuzzy PID compound control algorithm on MCU. The software of master computer was programmed based on MFC,it realized the serial communication of controller and PC. The data displayed on the PC with waveform that was more intuitive to analysis the control performance. The experimental results showed that there is a gap between actual control and Matlab simulation. Fuzzy control system had the better steady state but worse dynamic performance compared with PID control. The comparison between simulation and real system could make the students have a more intuitive un
