【摘要】 针对自动控制原理实验课存在的问题,进行了实验系统及实验方式的改革。采用半实物仿真方式,利用Simulink完成控制框图的搭建,开发了驱动程序,利用Matlab/RTW生成实时控制代码,直接控制数据采集板实现实时控制。学生在实验过程中能够迅速搭建控制系统,并且可以方便地修改参数及控制率、增加非线性因素等。通过实时代码的生成,快速实现,及时得到控制效果,理论的设计更加直观,激发学习兴趣。对实验内容进行了更新,增加设计性实验的比重,引导学生在实验中发现问题,解决问题,调动学生在实验中的主动性。增加与工程实际的联系,增加了PID控制器的设计及实现环节。实验方式上进行了改革,转变教师的角色,让学生成为实验的主角,重视学生的实际体验,以学生为中心,教师提供必要的理论及技术支持。在近几年的教学实践当中收到很好的效果,学生通过实验环节对理论有了更清晰的认识,在实验中深化了理论知识。更多还原

【Abstract】 A reform is proposed for automatic control experiment course. A hardware-in-the-loop simulation experiment system based on Matlab is introduced in this paper. Real-time code is automatically generated by RTW. Students can construct control system rapidly,and modify parameters and the law of control easily. Furthermore,the result of experiment can be obtained intuitively and quickly. Hardware includes a PCI multi-purpose data acquisition board and an experimental box including analog circuit. The content of experiment course is updated by adding some designing contents. According to the result of several years’ application,this semi-physical system is effective to attract student’ s interests. And through laboratory experiments teaching,understanding of the theory concept and practical ability are improved.更多还原
