摘　　要：针对计算机控制系统课程教学的实际需要以及工科学生实践能力的培养,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 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 can make the students have a more intuitive understanding of the theory and practice,and can achieve good learning effect.
