| Bibliography: | ZHAO Wenlong, HUANG Xun（College of Information Engineering, Nanchang Hangkong University, Nanchang 330063 , China） digital servo system; digital signal processor; genetic calculation; fuzzy-PID control According to the actual need of course teaching of computer control technology,and the training of engineering students＇ practical ability,a power servo digital system with the chip of TMS320F28335 as the controller was developed. At the same time it realized the application of genetic fuzzy PID compound control algorithm on MCU.The software of master computer was based on MFC,it realized the serial communication of controller and PC. The data display on the PC for waveform and form so that more intuitive could be obtained to analyze the control performance. The experimental results show that the actual control effect and the Matlab simulation has certain gap. Fuzzy control system has the better steady state but worse dynamic performance compared with PID control. The comparison between simulation and real system |
