摘　　要：开发了以TMS320F28335为主控芯片的数字随动系统控制器,实现了遗传计算模糊PID控制算法在微控制器上的应用。上位机软件采用MFC程序设计编写,实现控制器与PC机的串行通信,将给定量与反馈量在PC机上进行波形和形态显示,便于更直观地对其控制性能进行分析。实验结果表明,实际控制效果与Matlab仿真有一定的差距。遗传计算模糊PID控制与PID控制相比较,系统的稳态性能增强,动态性能减弱。仿真与真实系统的对比可以使学生对理论与实际有更加直观的认识和深入的理解,能够取得良好的学习效果。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 understanding of the theory and practice,and could achieve good learning effect.
